Question

The surface area of a sphere is 394.24 m².Find its radius and volume.

Answer 1

Surface area of sphere is = 4πr²
ATQ                    4πr²= 394.24
                          ⇒  r²= 31.26
                               r = 5.6 m
         Radius of sphere is 5.6 m
Volume of sphere v= 4πr³/3
                            = 4*π* (5.6)³/3
                            = 735.914 m³
         Volume of sphere is 735.914 m³
