What is the area of the circle in the figure below?

(169π)/4
(169π)/2
169π
(13π)/2
13π

Explanation

Answer: A - The area of the circle is 169π/4. The radius of the circle is equal to half of the diagonal AD. Find AD using the Pythagorean Theorem.

AD² = AC²+ CD²= 12²+5²= 144+25 = 169
AD=√169=13
r = AD/2 = 13/2
A = r² π = (13/2)² π= 169π/4
