Question

Me James has a cylindrical that measures 4 inches in diameter and are 9 inches high. What is the volume

Answer 1

The vol. of a cylinder of radius r and height h is V = pi*r^2*h.

Here, V = pi(2 inches)^2 * (9 inches)= 4*pi * 9 cubic inches.

You can write this as 36pi cubic inches, or use 3.14 for pi and come out with 113.10 cubic inches.

Answer 2

The formula you would use would be V=(3.14)r^2height
