Question

What is the volume of a hemisphere with a radius of 2.1 m, rounded to the nearest tenth of a cubic meter?

Answer 1

The volume of hemisphere is 19.4 cubic meter.

Explanation:

Given:

A hemisphere is with a radius of 2.1 m.

Now, to find the hemisphere volume with radius 2.1 m.

`Radius\ (r) = 2.1 m.`

So, we put formula to get the volume of hemisphere:

`Volume=(2)/(3) \pi r^3\ \ \ \ \ (Taking\ the\ value\ of\ \pi =3.14)\\\\Volume=(2)/(3) * 3.14* 2.1^3\\\\Volume=(2)/(3) * 3.14* 9.26\\\\Volume=19.384\ cubic\ meter.`

Hence, the rounded to the nearest tenth of a cubic meter is 19.4 cubic meter.

Therefore, the volume of hemisphere is 19.4 cubic meter.
