Pleas add a picture. At this moment I can not answer this question because vital information is missing.
Elena should put a point where the two circles intersect and draw line segments connecting that point to points A and B to finish her triangle.
(1 + x) (13) = 13+6.5
13x + 13 = 19.5
13x = 6.5
x = 0.5

The answer to this question is B. 130cm^2.
Using the volume formula for a sphere (V = (4/3)πr^3) you can plug in the values that we know to find the radius to be around 3.22117 cm. You can then use the area of a sphere formula (A = 4πr^2) to find the area. Hope this helps :)
