divide first the given diameter to obtain the radius
so 21.6/2 = 10.8cm
then use the formula to calculate the volume of the sphere = 4/3 π r^3
then use, vol. of sphere = (4/3)* (3.1416)*(3)^3 = 5276.669cm^3 or 5276.7cm^3
THEREFORE, THE ANSWER IS LETTER A.

I'm sorry the answer is 3166.0 cm^3 so either the answers are wrong or the question is wrong. If you want to check my working the formula for the volume of a sphere is 4/3 pi radius^3 and the radius of a sphere is half the diameter. The value of pi is 3.14. I hope you find out what's up with that...

radius of sphere = 21.6 / 2 = 10.8 cms
volume = (4/3) pi*r ^ 3
putting values of r
V = (4/3) (22/7) (1259.712) = 5278 . 793
you can take the answer option A to the nearest
