Question

Here are two circles, Circle A and Circle D. Segment AD connects the two centers and is 10 inches long. Segment AD is a side to square ABCD. What is the area of the shaded region.

Answer 1

Answer:

the answer is, area of the square - a half of area of the circle

C=circle and S =square

radius of C is 10

so Area Of C is =

$\pi r^{2} = \pi{10}^{2} = 100\pi$

area of S = 10×10 = 100

so the answer is

$s - \frac{c}{2} = 100 - \frac{100\pi}{2} = 100 - 50\pi$
