Answer:
A. 5 square inches
Step-by-step explanation:
The formula for the radius of a circle is r = square root of A over π
If you plug in 20 for A you would get 2.52 for r
2.52 divided in 2 is 1.26
To find to area of a circle of a circle with a radius of 1.26 use the formula
A= π(1.26)^2
solve and get
4.99 or 5
