=π10 2

=100π

Step 2: Find the area of 1/4 a circle

Area of 1/4 of the circle equals 1/4 * 100π

1/4 * 100 pi equals 100/4 pi

100 divided by 4 equals 25 pi

Answer:

Radius is r=10

Since the angle is 90 degree, this is 1/4 of a circle.

Area of a circle is A=πr²

1/4 of a circle is 1/4πr²

the area is 1/4πr² = 1/4π(10)² = 1/4π(100) = 25π
