The formula for the area of a circle is pi times the radius squared, so if the radius is 6 inches, that is pi times 36 square inches. Pi is approximately 3.1415, which gives us an area of 113.094 square inches. If that is not exact enough, pi has been worked out to thousands of decimal places, and can be easily looked up on Google.

What is the EXACT area of the circle having a radius of 11 miles?
The area of a circle is calculated using the formula ( A = \pi r^2 ), where ( r ) is the radius. For a circle with a radius of 11 miles, the area is ( A = \pi (11)^2 = 121\pi ) square miles. Using ( \pi \approx 3.14159 ), the exact area is ( 121\pi ) square miles, or approximately 380.132 square miles when calculated numerically.

What is the exact area of a circle whos diameter is 6 cm?
There is no way to find the exact area of a circle. The formula for the area is Pi times the radius squared. But Pi is an irrational number -- that is, no matter how many numbers you write it out to, you could always write it further. Since there is no exact value of Pi there can be no exact value of the area based on the diameter. The radius is half that of a diameter. Therefore, if you know the diameter you know the radius. In this case the radius is 3cm and the area of the circle = pi * 32 So the answer is roughly
