Question

A can of beans has a diameter of 8.2 cm and a height of 13cm. What is the volume of the can of beans (to the nearest tenth of a cubic centimeter)?

Answer 1

approx. 686.5
`cm^3`

Explanation:

Formula for the volume of a cylinder:

`V=\pi r^2 h`

r is the radius of the base, and h is the height.

h = 13 cm

The radius is half the diameter

r = d/2 = 8.2 / 2 = 4.1 cm

Putting these values into our equation:

`V=\pi *4.1^2 * 13 = \pi * 16.81 * 13 = \pi * 218.53`

`\pi * 218.53` ≈ 686.5
`cm^3`

Answer: approx. 686.5
`cm^3`
