Question

Volume of hemisphere is with radius 3cm

Answer 1

volume of hemisphere=2/3×pie×r3 (cube).

volume=2/3×22/7×3×3×3

= 2×22/7×9

=396/7

=56.4

volume of hemisphere=56.4

hope it will help you.

Answer 2

Concept

The formula will use to find the volume of a hemisphere is $\frac{2\pi r^3}{3}$.

Given

The radius of a hemisphere is 3cm.

To find

We have to find the volume of the hemisphere.

Solution

The hemisphere's radius (r) is assumed to be 3 units.

A hemisphere's volume is equal to 2πr³/3.

By replacing 'r' with the number nine, we get

A hemisphere's volume is equal to (2 π3³)/3.

A hemisphere's volume is equal to (2ₓ3.14 ₓ3³)/3.

As a result, the hemisphere's volume is 56.55 units³.
