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?
Choose the correct choice from the following options.
A) 1:8.
B) 1:2.
C) 1:24.
D) 1:64.
E) 1:6.
Given : The radius of A is 4 times as large as the diameter of B. =&gt; R(a) = 4*D(b) = 4*2*R(b) = 8R(b). The radius are in ratio of 1:8 thus the area will be in the ratio of square of radius. 1:64. Hence 1:64..
