Answer 1

the formula is 4πr^2

Answer 2

Hello my dear friend!!

———————————

Thanks for asking the question!!

The total surface area of sphere is :-

4pi r2.

Sorry,actually I m from web browser and I don’t have the mathematical denotions.

Let’s take an example to inderstand the problem:—

Question:-LET THE AREA OF A SPHERE BE 88/7. Then find it’s radius?

Answer:—

4pi r2=88/7

Pi r2=22/7

r2=22/7 x7/22

r= +-1

But as radius can’t be negative .

r=1.

Hence answer,
