## anonymous 5 years ago PLEASE HELP ME pleASSSSEEEE! :) If the sphere shown above has a diameter of 30 units, what is the volume of the sphere? A.)36,000π cubic square B.)4,500π cubic square C.) 3,600π cubic square D.)100π cubic square The picture is there when you click on the question :)

B.) 4500 * PI

ARE YOU SURE?

I can tell you why, if you interested.

$V = \pi/6 * d ^{3}$ so if the diameter is 30, then 30^3 = 27 000. Divide it by PI/6. The result is 51 566. But we have the answers 'x' times PI where x means 36 000, 4500 3600 or 100. So we have to divide the result by PI. The new result is 4500.
