Answer 1

Hi

Here is ur answer mate !!!!!!

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

Answer:

            r = 3.5 cm

Step-by-step explanation:

Surface area of a sphere = 4πr²

Given,

Surface area = 49π

Hence,

49π = 4πr²

(49π)/4π = r²

π will get cancelled out,

We get,

49 / 4 = r²

r² = 12.25

r = √ 12.25

r = 3.5 cm
