Question

what is T.S.A, C.S.A and Volume of sphere ?

appropriate answer only ⚠️​

Answer 1

Step-by-step explanation:

Curved Surface Area = 2πrh.

Total Surface Area = 2πrh + πr 2 + πr 2 = 2πrh + 2πr 2 = 2πr(r + h)

Volume = πr 2 h.

Answer 2

Answer:

I HOPE ANSWER WILL HELP YOU

Step-by-step explanation:

C. S. A= 2πrh.

T. S. A= 2πrh + πr 2 + πr 2 = 2πrh + 2πr 2 = 2πr(r + h)

VOLUME OF SPHERE = πr 2 h.
