Question

Find the volume of a hemisphere,its curved surface area is 77 sq.cm

Answer 1

Answer:

First of them

use the formula of curved surface area of hamisphere

ok.

n find the radius

then,

use the formula of volume ok

hope u understand

Answer 2

Answer:

Given: CSA of the hemisphere= 77m^2

Since, CSA of the hemisphere = 2/3πr^3

or, 77=2/3×22/7×r^3

then find the radius of the hemi.

use volume of hemisphere formula and put value of r you'll get the answer.

Hope you understand.
