Let r1 &r2 with the radii in the ratio of 2:3 resp.
r1:r2=2:3................................... (1)
Area (circle )=pie×r Sq.
Let A1&A2 be the areas of the two circles resp.
Since , area is directly proportional to r Sq.
Therefore, a1:a2 =r1 Sq. : r2 Sq.
a1:a2= [2:3] Sq.
a1:a2= 4:9
Hope this answer will help you in a way.
