# If the ratio between the radius of the circles is 4 : 3 then what is ratio of the area between the two circles:

 A) 13 : 17 B) 4 : 5 C) 16 : 9 D) 3 : 5

 C) 16 : 9

The ratio of radius of two circles is 4 : 3

Area of I circle = $$\Large \pi \times \left(4\right)^{2}= 16 \pi$$

Area of II circle = $$\Large \pi \left(3\right)^{2} = 9 \pi$$

Ratio of therir area between two circles

=$$\Large 16 \pi : 9 \pi = 16 : 9$$
