- Math. I really don't get this question -
**Steve**, Tuesday, December 10, 2013 at 11:24pmIf the radii of the circles are x,y,z then each side of the triangle is the sum of two of the radii. So,

x+y=8

x+z=9

y+z=13

(x,y,z) = (2,6,7)

Since the area of a circle is πr^2, the area of all of the circles is

π(2^2+6^2+7^2) = 89π
