Answer 2

Step-by-step explanation:

Two circles k1 and k2 intersect in such a way that outside their intersection is 10% of the area of the circle k1 and 60% the area of the circle k2. What is the ratio of the radii of the circles k1 and k2?

Statement of the given problem,

Two circles k1 and k2 intersect in such a way that outside their intersection is 10% of the area of the circle k1 and 60% the area of the circle k2. What is the ratio of the radii of the circles k1 and k2?

Let R1 & R2 denote the radii of the given circles k1 and k2 respectively.

Hence from above data we get following relation,

(100% - 10% =) 90% of area of circle k1

(100% - 60% =) 40% of area of circle k2

Therefore,

(90/100)*π*R1^2 = (40/100)*π*R2^2

or (R1/R2)^2 = 4/9

or R1 : R2 = 2 : 3
