1.

./mu ule sur race area or a spnere whose volume is 4851㎝··The surface area of a sphere is 346.5 cm2. Find its radius and hence its volume.

Answer»

Surface area of sphere = 4πr^2therefore A/Q4πr^2 = 346.5r^2 = 213444r = √213444 = 462 cm

volume = 4πr^3 /3=(4*22/7*462*462*462) /3= 413227584 cm^3
