Best ResponseYou've already chosen the best response.1When you double the diameter, you double the radius. V = (4/3)(pi)r^3, so new V is (4/3)(pi)(2r)^3, so the volume gets to be 8 times as much as the original.

Best ResponseYou've already chosen the best response.0let the dia be 'd' the ques says that the dia is doubled therefore the new dia is '2d' => radius of the new sphere is '2r' we know that, volume of spere is v,= (4/3) pie (radius)^3 = (4/3) pie (2r)^3 if you solve it u'll be getting ma ans

Best ResponseYou've already chosen the best response.1(4/3)(pi)(2r)^3 = (4/3)(pi)(2^3)(r^3) = (4/3)(pi)8(r^3) = 8(4/3)(pi)(r^3) = 8 times original volume.
