. Yes, you can find the circumference of a circle if you know the radius. The circumference of a circle is calculated by using the formula C=2pi*r, where r is the radius and pi is a constant ratio (roughly 3.14). In this example, you would calculate the circumference by using C=2*3.14*100, which equals 628.4 ft.
