Question

the surface area of sphere is 5544m square find its radius
also find volume

Answer 1

4πr2 = 5544cm2
4×22/7×r2 =5544
r2 = 441
r = 21cm

Now
Volume = 4/3πr3
= 4/3 × 22/7 ×21×21×21
= 38808cm3

Answer 2

r= 1/2.a/2 underoot =1/2.5544/pie ( 22/7) = 21.00423.
r= 21
now , volume of sphere =4/3 ×22/7×21 ×21 ×21=
4×22×441= 88×441=38808 cubic centimeters
