# Find The Ratio of C1 and C2 ? if

**Answer: (2) 4/25**

Explanation:-

In the figure-

**Triangle is a right triangle-**

Therefore, the radius of big circle = 5/2

Then, R = 5/2

Radius of encircle or small circle = Area of the triangle/ semi perimeter

= 1 x 4 x 3 /6 x 2

= 1

Then, the ratio of the area of C1 and the area of C2 = 1^2/(5/2)^2

= 4/25

Hence, the answer is (2) 4/25.
