How do you calculate pi r 2?
The area of a circle is pi times the radius squared (A = π r²).
Pi is sometimes given the value 22 over 7 which is approximately 3.14. For a more accurate approximation, you should have a pi button on your calculator. The formula for area equals pi times the radius squared, R stands for the radius measurement of the circle. So the formula is area equals pi R squared.
