Answer:
This is 1/4 of a circle and we know since the angle is a right angle.
SInce we need the area we can find the area of the “full” circle and then divide that by 4 to find the section of this circle.

The formula is
A=πr^2

Radish is 2.
2^2=4
SInce we have 3.14 for π
A=3.14(4)
12.56=a

Divide by 4

12.56/4= 3.14

3.14 is the area.
