Inscribed rectangle

The circle area is 231. Determine the area of the inscribed rectangle with one side 13 long.

Final Answer:

S2 =  145.41

Step-by-step explanation:

S1=231 a=13  S1 = π r2 r2 = S1/ pi r2 = a2/4 + b2/4 4 r2 = a2 + b2 b2 = 4 r2  a2 b=4 (S1/π)a2=4 (231/3.1416)13211.1856  S2=a b=13 11.1856=145.41
