Question

I need help please! If you know the answer can you explain?

Answer 1

Answer:

h = 8.00 inches , which is answer B

Step-by-step explanation:

The formula to calculate the Volume V of a cone is:

V = 1/3*pi*r²*h

Given:

V = 33.5 in³ pi = 3.14 and r = 2 in

This time the Volume is given, but you need to calculate the height h. So let's rewrite the formula, so it starts with h =

V = 1/3*pi*r²*h

multiply left and right of the = sign by 3

3/3*pi*r²*h = 3*V

divide left and right of the = sign by pi*r²

h = 3*V/(pi*r²)

V = 33.5 in³

pi = 3.14

r = 2 so r² = 4 in²

h = 3*33.5/(3.14*4)

h = 8.00 inches , which is answer B
