Question

A cylinder has a radius of 19 millimeters. Its volume is 22,670.8 cubic millimeters. What is the height of the cylinder?

Answer 1

20.00 mm to the nearest hundredth.

Explanation:

V = π r^2 h

22,670.8 = π * 19^2 * h

h = 22,670.8 / π * 19^2

= 22,670.8 / 1134.115

= 19.9899

Answer 2

19.99

Explanation:

use the formula

`\pi {r}^(2) h = v`

change it up so that you solve for height

`\frac{v}{ {r}^(2) * \pi } = h`

substitute values in and solve
