Answer 1

Answer:

Volume of hemisphere is equals to 1071.78666 cubic unit

Step-by-step 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)$=\frac{2}{3} (\pi)r^3$ 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)= $\frac{2}{3} \pi r^3 =\frac{2}{3} \cdot 3.14 \cdot (8)^3$

∴ $V=\frac{2}{3}\cdot 3.14 \cdot 512$ =1,071.78666 cubic unit.
