Question

Curved surface area of solid sphere is 24cm2 if the sphere is divided into two hemisphere then the total surface area of one of the hemisphere is

Answer 1

Answer:

18 cm²

Step-by-step explanation:

Hi,

Given that curved surface area of solid sphere is 24 cm²,

But, if 'r' is the radius of the sphere, we know that curved surface

area = 4πr²

Thus, 4πr² = 24

Given that the sphere is divided into 2 hemisphere, then the

total surface area will be equal to half the curved surface area of

the sphere + Area of the hemispherical base

= 2πr² + πr²

=3πr²

=3/4*(4πr²)

=3/4*24 = 18 cm².

Hope, it helped !
