The volume of a sphere is 38808cm cube find its radius

Volume of sphere = 4/3 pi. r^3

38808 = 4/3 x 22/7 x r^3

11 x 3528 = 4/3 x 22/7 x r^3

3528 =4/3 x 2/7 x r^3

4 x 882 = 4/3 x 2/7 x r^3

882 = 2/21 x r^3

r^3 = 882 x 21 /2 = 441 x 21

= 21 x 21 x 21

hence ,

r = 21 cm

now,

surface area = 4 pi. r^2

= 4 x 22/7 x 21 x 21

= 4 x 22 x 3 x21

= 88 x 63 =5544 cm^2

Hope this helps! :)

8 2/3 is the answer

step-by-step explanation: just use a calculator

the answer is 11.2 (i know i’m late)
