Question

A hemisphere has 3 cm radius , find its volume?

hintHint:

Volume of hemisphere is 2 over 3 pi r cubed.

The correct answer is: 56.54


    Explanation:
    • We have given radius of hemisphere 3cm.
    • We have to find the volume of the hemisphere.
    Step 1 of 1:
    We have given the radius of the hemisphere 3cm
    So, The Volume will be

    V equals 2 over 3 pi 3 cubed

    equals 2 pi cross times 9
    equals 56.54
