Question

volume of a solid hemisphere is
$1152\pi$
cm³. find csa.​

Answer 1

Answer:

=288π cm

2

Step-by-step explanation:

Correct option is A)

We have,

V=1152π cm

3

We know that the volume of the hemisphere

=

3

2

πr

3

So,

3

2

πr

3

=1152π

r

3

=1728

r=12 cm

We know that the curved surface area of the hemisphere

=2πr

2

So,

=2π12

2

=288π cm

2

Hence, this is the answer.
