Question

if curved surface area of sphere is 36π cm², then find the volume
of the sphere​

Answer 1

Answer:

Volume of the Sphere ( V ) = 14.14 Cm³

Given that ;

CSA of Sphere = 36πcm²

CSA of Sphere = 4πr²

4πr² = 36πcm²

4r² = 36

4r = √ 36

r = 6 / 4

r = 3 / 2

Volume of the Sphere ( V ) = 4 / 3 π r³

4 / 3 × π × 3 / 2 × 3 / 2 × 3 / 2

2 × π × 3 / 2 × 3 / 2

π × 3 × 3 / 2

π × 9 / 2

3.14 × 4.5

14.14 Cm³

Hence ;

Volume of the Sphere = 14.14 Cm³
