Question

Suppose you are looking to purchase some cans to use for food storage. The can you are looking at has a diameter of 5in. and a height of 7in. What is the volume of the can? Round to the nearest hundredth

Answer 1

The volume of a cylinder is given by

V = pi r^2 h where r is the radius and h is the height

We are given the diameter is 5

r = d/2 = 5/2 = 2.5 in

V = pi ( 2.5)^2 (7)

V =pi ( 6.25)*7

V = 43.75 pi

Assuming a value for pi of 3.14

V =137.375 in ^3

Rounding to the nearest hundredth

V = 137.38 in ^3

Assuming a value for pi by using the pi button

V = 137.44468

Rounding to the nearest hundredth

V = 137.44 in ^3
