Two circular road signs are to be painted yellow. If the radius of the larger sign is twice that of the smaller sign, how many times more paint is needed to paint the larger sign (assuming that a given amount of paint covers the same area on both signs)?
A. 2
B. 3
C. pi
D. 4
E. 3pi/2
OA:D
Larger circle area is 4 times the smaller circle.(Since the ratio of radius is 2:1)
But,since the problem is asking how many times more I subtracted the area of smaller circle and picked.
If the question would have asked how many times,I would have easily picked D as the answer
Experts can you please explain where is my GAP?
