The … WebMar 15, 2024 · Circumference is the distance around the circle (its perimeter), and area is the space inside the circle. C = π*D or C = 2*π*r. A = π*r². The two options for the circumference equation are, in fact, equivalent, since D = 2r. You may be wondering why mathematicians split the 2 and the r around the π, instead of just saying π2r.
