Answer:
Step-by-step explanation:
1. Find the circumference of the cylinder: C = 2πr
2. Multiply this result by the height of the cylinder: A = 2πr·h
3. To this result add the surface areas (there are two) of the ends of the cylinder: 2πrh + 2πr²
This is the correct general formula for the surface area of a cylinder of radius r and height h. If you want specific numbers, please share the values of r and h.

A rectangle prism has a base with an area of 20 square centimeters and a height of 3 centimeters. What is the volume of the prism?
Answer:
Step-by-step explanation:
The volume of a rectangular prism is shown below:
We are given the an area of
173.6
cm
and a height of
9
cm
.
We also know that the formula for area is
l
w
, meaning we can substitute the area for
l
w
in the volume formula.
Now let's plug in what we know into the formula and solve for the volume:

=
(
173.6 cm

)
(

A man is five times as old as his son. Four years ago the man was thirteen times as old as his son.
Find their present ages.
Answer:
Age of son = 6 years
Age of man = 5×6 = 30 years
Step-by-step explanation:
GIVEN :-
A man is 5 times as old as his son. (In Present)4 years ago , the man was 13 times as old as his sonTO FIND :-
The present ages of the man & his son.SOLUTION :-
Let the present age of son be 'x'.
⇒ Present age of man = 5x
4 years ago ,
Age of son = (Present age of son) - 4 = x - 4
Age of man = (Present age of man) - 4 = 5x - 4
The man was thirteen times as old as his son. So,
[tex]=> 5x - 4 = 13(x - 4)[/tex]
Now , solve the equation.
Open the brackets in R.H.S.[tex]=> 5x - 4 = 13x - 52[/tex]
Take 5x to R.H.S. and -52 to L.H.S. Also , take care of their signs because they are getting displaced from L.H.S. to R.H.S. or vice-versa.[tex]=> 13x - 5x = 52 - 4[/tex]
[tex]=> 8x = 48[/tex]
Divide both the sides by 8[tex]=> \frac{8x}{8} = \frac{48}{8}[/tex]
[tex]=> x = 6[/tex]
CONCLUSION :-
Age of son = 6 years
Age of man = 5×6 = 30 years

How many unit cubes are used to build the solid?
unit cubes are used to build the solid.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the views are not shown.
So, I will answer this question with the attached views of a rectangular prism.
Required
The number of cubes used
For the attached views of the rectangular prism, we will make use of the following representations
Top view [tex]\to[/tex] Width
Front view [tex]\to[/tex] Height
Side view [tex]\to[/tex] Length
So, we have:
[tex]Width = 2 units[/tex]
[tex]Height = 6 units[/tex]
[tex]Length = 1\ unit[/tex]
The number of cubes is calculated by solving for the volume of the prism.
For a rectangular prism, the volume is:
[tex]Volume = Length * Width * Height[/tex]
[tex]Volume = 2 * 6 * 1[/tex]
[tex]Volume = 12[/tex]
This implies that 12 cubes were used to build the solid.

Answer:
A
Step-by-step explanation:
If the price of a hot dog is x, then the price of two hot dogs is 2x, and the price of 3 of them is 3x.
If the price of a drink is y, then the price of 2 drinks is 2y.
So, we have the price of 2 hotdogs and 2 drinks is 4.75.
2x + 2y = 4.75
And the price of 3 hot dogs and 1 drink is 7.75.
3x + y = 7.75
This pair of equations matches those in choice A.
_____
Comment on the question
We know right away that something is screwy here, because the cost of two hotdogs and 2 drinks should be an even number. 4.75 is not an even number. If we solve this set of equations, we find the cost of a drink is negative—not something you're likely to see in the real world.
So, this is an exercise in writing equations. It has nothing to do with finding real prices.

Several cheeses are for sale. The cheese comes in wedges shaped like sectors of a circle. All of the wedges are the same height. Tyler bought a wedge. He measured the arc length of the wedge to be 12 cm and the radius to be 8 cm. Priya bought a wedge that came from a circular cheese block with radius 9 cm. The block was cut into 6 congruent sectors. Whose wedge is larger? Explain or show your reasoning.
Tyler's wedge is larger
The arc length of Priya's wedge is only 9.42, and Tyler's is 12
Tayler's wedge is larger.
What is arc length?"Arc length is the distance along the part of the circumference of any circle."
Formula to calculate the circumference of a circle:S = 2 × π × r
where, r is the radius of the radius of a circle
In this question,
Tyler bought a wedge shaped cheese with arc length 12 cm and radius 8 cm.
Priya bought a wedge that came from a circular cheese block with radius 9 cm and the block was cut into 6 congruent sectors.
The circumference of circular cheese block with radius 9 cm would be,
⇒ s = 2 × π × 9
⇒ s = 18π cm
Since, the block was cut into 6 congruent sectors.
The arc length of each block would be, 18π / 6 = 3π cm
That is, 9.43 cm
Since 12 > 9.43, Tayler's wedge is larger.
