Question

The volume of a cylinder is 785 m^3 If the

height is 10 meters, calculate the radius of
the cylinder

Answer 1

5 m

Explanation:

We know the volume of a cylinder is given by the expression

`V= \pi r^2 h`. Let's replace what we know, and find the missing data:

`785 = \pi r^2 * 10 \rightarrow r^2 = \frac {785}{10\pi} = 25\\r= 5`

Taking only the positive value of the square root since it's a length.
