The radius of a circle is 9 feet. What is the circle's area?
The area of the circle is 254.47 square feet (rounded to two decimal places).
Explanation:
The formula to find the area of a circle is A = πr^2, where A is the area and r is the radius.
In this case, the radius is given as 9 feet, so we can substitute that value into the formula:
A = π(9)^2
A = π81
A ≈ 254.47
So the area of the circle is approximately 254.47 square feet.
