17. What's the radius of a circle with an area of 64 square feet? A. 4.51 ft. B. 20.38 ft. C. 41.5 ft. D. 5.41 ft.
Question
Solution 1
The area of a circle is given by the formula A = πr², where A is the area and r is the radius.
Given that the area A is 64 square feet, we can solve for r as follows:
64 = πr²
Divide both sides by π:
64/π = r²
Take the square root of both sides to solve for r:
r = √(64/π)
