Answer:

16π ft²

Step-by-step 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

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.
