Question

if the surface area of a sphere is 5544 cm2 find the volume

Answer 1

HELLO DEAR,


SURFACE AREA OF SPHERE = 4 π r2



5544=4x22/7xr​2




5544x7/4x22=r2


r2=441




r=21cm


NOW,



.VOLUME=4/3 π r3
         
     =  4/3x22/7 x21x21x21
​          

    =38808 cm3

I HOPE ITS HELP YOU DEAR,

THANKS
​        

Answer 2

surface area of sphere A=4pir^2
but surface area A=5544 cm2
then, 4pir^2=5544
r^2=5544/4x3.14
r=root of 441.40
r=21.009 cm
volume of sphere V=4pir^3/3
V=4x3.14x(21.009))^3/3
V=9262.19x16.56/3
V=116333.1064/3
V=3877.8cm^3
