40 points of you can answer this question. What is the volume of a hemisphere with a radius of 8

Answer 1

Volume of hemisphere is equals to 1071.78666 cubic unit

Explanation:

Given: radius of hemisphere=8 unit

A hemisphere is a 3-dimensional object that is half of a sphere.

Volume of hemisphere is equal to two thirds multiplied by pi multiplied by radius to the power 3.

Formula: Volume of hemisphere(V)
`=(2)/(3) (\pi)r^3` where r is the radius of the hemisphere and the value of pi is constant i.e,
`\pi=3.14`

Now, substitute the value of r to find the volume of hemisphere,

Volume of hemisphere(V)=
`(2)/(3) \pi r^3 =(2)/(3) \cdot 3.14 \cdot (8)^3`

∴
`V=(2)/(3)\cdot 3.14 \cdot 512` =1,071.78666 cubic unit.
