Answer:
About 63,617 ft²
Explanation:
[] The area of a circle is equal to πr²
π(225)² ≈ 159,043
[] To find 40%, we can multiply our whole by 40%
-> 40% divided by 100, 0.4, becomes a decimal
159,043 * 0.4 = 63,617
-> Don't forget to add on the units once you are done, this problem was done in feet, since it is an area we used feet squared
Have a nice day!
