2 answers:
Answer:
The area of the shape is 25π unit
Step-by-step explanation:
Step 1: Find the area of the full circle
=πr 2
=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
