Since the diameter = 2 × radius, we can also use the following equation to find circumference: C = π × 2r or C = 2 π r. Circumference, radius and diameter of a circle are all distance measurements. Therefore, the units are cm, mm, m, km, etc. Examples: 1. A toonie has a radius of 1.4 cm. a). Find the diameter Answer: d = 2 × r
