The area of a circle is pi times (radius squared) Thus if radius is one inch then area is (pi) times (1) times (1) = pi = 3.1416 inches squared
1 inch
It is because your 1 inch is one circle 1 inch one circle one of each get it.
Calculate the radius, which is simply 1/2 the diameter. Then use the standard formula for the area of a circle. ________________________________________________________________ The circle area = (pi) x diameter / 4 = 3.14 x 25/4 = 19.625 Sq inch
Multiply the radius by (2 x pi).
