Find the area of the striped sector if ∠ a = 45° and the circle has a radius of 10 inches.

a)25π
b)5π over 4
c)5π over 2
d)25π over 2

A diagram must be provided along with the question above. Based on my research, here is what I got.

100 pi is the area of the entire circle
 That makes :
∠ A = 45°/360 = 1/8
 100pi/8 = 25 pi / 2
 
The answer is option D)25π over 2. I hope this answer helps.
