It is: pi*12.52 square mm
A circle with a diameter of 25 mm has an area of 490.9 square mm.
490.9 square inches for a 25-inch diameter circle.
The exact area is 625*pi. Since pi is an irrational number, any exact answer must include pi and may not contain a decimal (or rational) approximation of pi.
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
