a and b are two circles. the radius of a is four times as large as the diameter of b. what is the ratio between the areas of the circles?
divide(power(const_1, const_2), power(multiply(const_2, const_4), const_2))
given : the radius of a is 4 times as large as the diameter of b . = > r ( a ) = 4 * d ( b ) = 4 * 2 * r ( b ) = 8 r ( b ) . the radius are in ratio of 1 : 8 thus the area will be in the ratio of square of radius . 1 : 64 . hence d .
