Question

Area of the shaded segment of a circle. radius is 10 arc measures 90 degrees

Answer 1

`25\pi` or about 78.54 units

Explanation:

Since the arc measures 90 degrees, since 90/360=1/4 the segment is 1/4 of the area of the circle. The whole area of the circle is
`\pi 10^2=100\pi`, meaning that the area of the segment is
`25\pi` square units, or about 78.54. Hope this helps!
