A = pi r^2 / 2
if 22mm = radius
then
A = (3.14 * 22^2) / 2
A = 759.88
if 22mm is the diameter
then
A = (3.14 * 11^2) /2
A = 189.97
If you mean two of the same numbers that add to make 75, it's 37.5 ....?
Keep diving each of them by a number and see if it matches. For example I have 25, 50, and 100. The gcf is going to be 5.
