50.27 would be the answer.
To solve the area of a circle, use the formula a=pir^2. So, it's a=pi4^2. 4x4 is 16, 16x3.14/pi is 50.27. So the answer is 50.27 feet.
Answer:
16π ft²
Explanation:
Area of a circle can be found simply by applying the formula:
Area = πr²
Area of a circle with radius 4 feet
= π(4)²
= 16π
If we are evaluating the answer with π:
Using π as 3.142,
Area
= 16(3.142)
= 50.272 ft²
