"The cone and cylinder above have the same radius and height..."
the volume of the cone = 210 cubic centimeters
Formula
The formula for the volume of a cylinder is V=Bh or V=πr2h. The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h.
How to solve
Given radius and height calculate the volume, lateral surface area, and total surface area.
Calculate V, L, A | Given r, h
use the formulas above
Given radius and volume calculate the height, lateral surface area, and total surface area.
Calculate h, L, A | Given r, V
h = V / πr2
Given radius and lateral surface area calculate the height, volume, and total surface area.
Calculate h, V, A | Given r, L
h = L/2πr
Given the height and lateral surface area calculate the radius, volume, and total surface area.
Calculate r, V, A | Given h, L
r = L/2πh
Given height and volume calculate the radius, lateral surface area, and total surface area.
Calculate r, L, A | Given h, V
$r = √( V / πh )

The orbit of the space is approximatly a circle with a radius of 4100 mi. How far do the astronauts travel with each orbit?
Answer:
25748 km
Step-by-step explanation:
The distance at which astronauts travel can be obtained by calculating the Circumference of the circle.
Circumference of a circle = 2πr ; π = 3.14
Radius = 4100 km
Circumference of a circle = 2 * 3.14 * 4100
Circumference of the circle = 25748 km
Hence, astronauts travel a distance of 25748 km

This sphere has a diameter of 5 m.
A sphere with diameter 5 meters.
What is the volume of the sphere?
Answer:
65.45m^3
Step-by-step explanation:
volume = 4/3 * pi * radius ^3
v= 4/3 * pi* 2.5^3
v= 4/3* 22/7* 15.625
v= 64.45 m ^ 3
When rolling a six-sided number cube and flipping a
coin, what is the probability of landing on tails and a
multiple of 3?
Answer:
There is a one in six chance of rolling a six and a one in two chance of getting tails. We can write this in mathematical notation as:
Let the result of the dice role = d
Let the result of the coin toss = c
prob (d=6)∩ prob (c= tails )
=16∗12
=112
The ∩ symbol means the intersection of two events. When we want the probability of event x AND event y occurring, we multiply their probabilities. This is called the intersection of x and y.

Find the value’s of x given that f(x) = x^2 - 2x - 3 and f(x) = 5
Answer:
4 and - 2
Step-by-step explanation:
f ( x ) = x^2 - 2x - 3
f ( x ) = 5
x^2 - 2x - 3 = 5
x^2 - 2x - 3 - 5 = 0
x^2 - 2x - 8 = 0
x^2 + 2x - 4x - 8 = 0
x ( x + 2 ) - 4 ( x + 2 ) = 0
( x - 4 ) ( x + 2 ) = 0
x - 4 = 0
x = 4
x + 2 = 0
x = - 2
x has 2 values,
x = 4, - 2

Answer:
x = 43
Step-by-step explanation:
First, make the equation which is
x + 49 + 88 = 180
Next, add 49 + 88 which is 137
Now you have x + 137 = 180
Subtract 137 from both sides and you get your final answer:

Erica is studying two number patterns. Pattern A starts at 0 and has the rule "add 5." Pattern B starts at 0 and has the rule "add 10." What is the relationship between corresponding terms in the two patterns? The terms in Pattern B are 5 times the corresponding terms in Pattern A. The terms in Pattern B are 2 times the corresponding terms in Pattern A. The terms in Pattern B are one half the corresponding terms in Pattern A. The terms in Pattern B are one fifth the corresponding terms in Pattern A.
Answer:
The terms in Pattern B are 2 times the corresponding terms in Pattern A
Step-by-step explanation:
Given
Pattern A
[tex]Start = 0[/tex]
[tex]Rule: Add\ 5[/tex]
Pattern B
[tex]Start = 0[/tex]
[tex]Rule: Add\ 10[/tex]
Required
The relationship between both patterns
First, we calculate the nth term of both pattern.
For A
[tex]A(n) = Start + Rule[/tex]
[tex]A(n) = 0 + 5n[/tex]
[tex]A(n) = 5n[/tex]
For B
[tex]B(n) = Start + Rule[/tex]
[tex]B(n) = 0 + 10n[/tex]
[tex]B(n) = 10n[/tex]
So, we have:
[tex]A(n) = 5n[/tex]
[tex]B(n) = 10n[/tex]
B(n) can be expressed as:
[tex]B(n)=2* 5n[/tex]
Substitute [tex]A(n) = 5n[/tex]
[tex]B(n)=2* A(n)[/tex]
This means that the term of B(n) is twice the corresponding term of A(n)

Carter is creating quilt pieces in the shape of a kite as shown below. One of the kite diagonals measures 6 inches, and the area of each piece must be between 20 and 25 square inches.
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]d_1 =6in[/tex] --- the first diagonal
[tex]Area = (20in^2,25in^2)[/tex]
The question is incomplete, as the image of the kite and what is required are not given
However, a possible question could be to calculate the length of the other diagonal
Calculating the length of the other diagonal, we have:
[tex]Area = 0.5 * d_1 * d_2[/tex]
Make d2 the subject
[tex]d_2 = \frac{Area }{0.5 * d_1}[/tex]
Multiply by 2/2
[tex]d_2 = \frac{2 * Area }{2* 0.5 * d_1}[/tex]
[tex]d_2 = \frac{2 * Area }{1 * d_1}[/tex]
[tex]d_2 = \frac{2 * Area }{d_1}[/tex]
When Area = 20, we have:
[tex]d_2 = \frac{2 * 20}{6}[/tex]
[tex]d_2 = \frac{40}{6}[/tex]
[tex]d_2 = 6.67[/tex]
When Area = 25, we have:
[tex]d_2 = \frac{2 * 25}{6}[/tex]
[tex]d_2 = \frac{50}{6}[/tex]
[tex]d_2 = 8.33[/tex]
So:
[tex]d_2 = (6.67,8.33)[/tex]
This means that the length of the other diagonal is between 6.67in and 8.33in
