the square foot? are you sure this isn't a biology question?

If 7 feet refers to the diameter, multiply that by pi.

The area of a circle is the number pi multiplied by the square of the radius of the circle. The radius is half the diameter. Therefore, the area of the specified circle is pi(3.5)2 = 38 square feet, to the justified number of significant digits. The last digit in the answer is depressed because it may not be accurate within 1 unit, if the diameter of 7 is accurate to only one significant digit.

diameter= 5m radius= diameter/2 = 5/2 =2.5m area of the circle= πr*r =22/7*2.5*2.5 =19.64....m

It is: pi*3.5 squared inches
