When the diameter of a sphere is decreased by 25 percent by what per cent does its curved surface area decrease?
Surface area, S.A., of a sphere with radius r equals to 4pir2.Since the diameter is decreased by 25%, the radius is also decreased by 25%.That is r - 0.25r = 0.75r.So that S.A. = 4pi(0.75r)2 = 2.25pir2
