Identify the lateral area and surface area of a right cone with radius 6 cm and slant height 13 cm.
Answer:
The lateral surface area is about = 269.747749 m squared
The surface area is about = 382.787749 m squared
Step-by-step explanation:
Answer:
L = 245 cm2 ; S = 358.1 cm2
Step-by-step explanation:
The lateral area of a right cone with radius r and slant height l is L=πrl.
The figure shows a right cone.
Apply the formula for the lateral area of a right cone L=πrl.
Substitute the known values for the radius r=6 cm and the slant height l=13 cm.
L=π(6)(13)=78π
Use a calculator to approximate. Round your answer to the nearest whole number.
L≈245
The lateral area of the cone is 245 cm2.
The surface area of a right cone with lateral area L and base area B is S=L+B, or S=πrl+πr2.
Substitute the given value for the radius r=6 cm into the formula for the area of a circle, B=πr2.
B=π(6)2=36π
Therefore, the base area is 36π cm2.
To calculate the surface area of the cone, substitute the known values into formula for surface area.
S=78π+36π=114π
Use a calculator to approximate. Round your answer to the nearest tenth.
S≈358.1
Therefore, the surface area of the cone is about 358.1 cm2.
Subtract. Use models if needed.

For Tammy's wedding she wants to
purchase $80 flower centerpieces to put on
tables. The flower shop will also charge her
$35 for delivering the centerpieces. If Tammy
has a budget of $1000 to decorate the tables,
how many centerpieces can she buy?
Answer:
She can only buy 12 centerpieces.
Step-by-step explanation:
To solve this question, we must first create an expression. We know that the total would be $1000. The delivery is included in that budget and it is a constant. EACH centerpiece is $80. From that information, you can build an expression.
80c + 35 = 1000
-------------------------------------
Next, you will need to solve for c, or any variable you choose. If you solve it, you will be left with:
c= 12.06
--------------------------------------
Since you cannot buy a fraction of a centerpiece, this concludes that the answer would be 12.
Good Luck!!

Genny is arranging flowers in vases for every 1 rose shes uses 6 tuilps .How many tulips would she use for every 5 roses
Answer:
30
Step-by-step explanation:
Ah okay, so this is a simple proportion.
If 1 rose = 6 tulips, then you just multiply however many roses you have by 6. So in your case, 5 x 6 = 30. So in short, for every 5 roses Genny uses, she will use 30 tulips.
Answer:
30 tulips
Step-by-step explanation:
This question gives us the amount of tulips for one rose.
Let us make 1 rose as r and a tulip is t. Now write an equation for the tulips.
Tulip = 6r
If we have 5r:
5r = 6t x 5
Solve!
5r = 30t
5 roses = 30 tulips

There are 360 seals. Of them are 9/20 are pups. The rest are adult seals . How many pups are the beach .
Answer:
162 pups are on the beach
Step-by-step explanation:
9/20 of 360
The key word "of" tells us to multiply
Variable x = number of pups
9/20 × x/360
Cross multiply
9 × 360 = 20 × x
3,240 = 20x
Divide both sides by 20
162 = x
Check our work:
9/20 = 162/360
Cross multiply
9 × 360 = 20 × 162
3,240 = 3,240
Correct
Is a parabola a one-to-one function?
Answer:
no
Step-by-step explanation:
The function f(x)=x2 is not one-to-one because f(2) = f(-2). Its graph is a parabola, and many horizontal lines cut the parabola twice. The function f(x)=x 3, on the other hand, IS one-to-one. If two real numbers have the same cube, they are equal.

Manuel incorrectly claimed that the surface area of the cylinder
shown is about 621.7 in.. Use a formula to find the surface area of the cylinder.
Use 3.14 for it. What was his likely error?
11 in
The surface area of the cylinder is about
(Round to the nearest tenth as needed.)
Answer:
25.9%
Step-by-step explanation:
Since, the actual dimensions of the cylinder is not given we can assume the some dimension to explain the problem
Let us assume the dimension of the cylinder be
radius= 3in
height= 5 in
The expression for the total surface area of a cylinder is
T. S. A. =2πrh+2πr^2
Let us plug in the values to to find TSA
T. S. A. =2×3.14×3×5+2×3.14×3^2
Solving we get
T. S. A. =94.26+56.556
T. S. A. =150.816 in^2
Now let us find the error
we know that error % is calculated as
%error= [actual value-expected value/expected value]×100
%error= [190 -150.816/150.816]×100
%error= [39.184/150.816]×100
%error= 0.259×100
%error= 25.9%

A collar of Styrofoam is made to insulate a pipe. Find its volume. The large radius R is to the outer rim. The small radius r is to the edge of the insulation. Use pi ≈ 3.14 r=2 R=4 h=20
Answer:
753.6 cubic units
Step-by-step explanation:
A collar of Styrofoam is made to insulate a pipe. Find its volume. The large radius R is to the outer rim. The small radius r is to the edge of the insulation. Use pi ≈ 3.14 r=2 R=4 h=20
The volume of the pipe formula is given as:
Use pi ≈ 3.14 r=2 R=4 h=20
Volume =h × π (R² -r²)
Volume =20 × 3.14 × (4² - 2²) cubic units
Volume = 62.8 × ( 16 - 4) cubic units
= (62.8 × 12 )cubic units
= 753.6 cubic units
Chris can do 30 pushups in 60 seconds. At this rate
how many pushups can he do in 360 seconds?
Answer: 180 pushups
Step-by-step explanation: First set up a proportion. The proportion would be 30 pushups over 60 seconds equal x over 360 seconds. Then you would cross multiply which is 60 times x which is 60x .After that do 30 times 360 which is 10,800.Now you have 60x = 10,800.NOw divide both sides by 60 which gives you 180 as x.

The diagonal of a cube is 20 cm. Identify the length of an edge. Round to the nearest tenth, if necessary.
answers:
20 cm
14.1 cm
13.8 cm
11.5 cm
The length of an edge or side length of the cube is 11.5 cm if the diagonal of a cube is 20 cm option (d) is correct.
What is a cube?It is defined as three-dimensional geometry that has six square faces and eight vertices.
We have a cube.
The diagonal of a cube is 20 cm.
Let a be the side length of the cube.
As we know, from the Pythagoras theorem we can calculate the length of the face diagonal.
Pythagoras' theorem can be defined as the square of the hypotenuse in a right-angled triangle equal to the sum of the squares of the other two sides.
Length of a face diagonal = √2a
Length of body diagonal = √3a
√3a = 20 (given)
a = 20/√3
a = 20/1.732
a = 11.5 cm
Thus, the length of an edge or side length of the cube is 11.5 cm if the diagonal of a cube is 20 cm option (d) is correct.
