Best Answer

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.
