Question

What is the volume of the cylinder below?

Answer 1

r=7
area of a circle= pi x r^2
so area of top face=49pi
multiply by height to find area
so 49pi x 10= 490pi units^3

Answer 2

490 pi units^3

Explanation:

The volume of a cylinder is given by

V = pi r^2 h

The diameter is 14 so the radius is 14/2 = 7

V = pi (7)^2 * 10

V =490 pi
