What is your answer using the radius?

Answered by Adrian
im not sure how to solve this problem at all
Answered by Ms. Sue
Solve it the same way you solved # 3.

V = pi * r^2 * h

See the website above for more explanation.

Answered by Adrian
divide the left and right side of the equation by ð r^2

V / (ð r ^2) = h ?
Answered by Ms. Sue
You need to find the volume of the cylinder. Use the volume formula above.
