Question

What is the volume of a cylinder with a base radius of 2 and height of 6 ?

Answer 1

Explanation:

V=pi r^2 h

r = 2

h = 6

V = 3.14 * 2 * 2 * 6

V =75.36

Answer 2

V = 24pi

or 75.36 ( using 3.14 for pi)

or 75.39822369 ( using the pi button)

Explanation:

The volume of a cylinder is given by

V = pi r^2 h

We know the radius and the height

V = pi (2)^2 * 6

V = pi 4*6

V = 24 pi

If we approximate pi by 3.14

V = 3.14 * 24 = 75.36

If we use the pi button

V =75.39822369
