To find the circumfrance of a circle, you need to multiply 2 times pi, times the circle's radius. If you don't know what that is, you multiply two times pi, and pi equals 3.14, and then multiply that by the radius, which is the measurement of half the circl'e diameter. the diameter is the distance from one side of the circle, to the exact opposite. you measure this with a ruler. HALF the measurement of the diameter is the radius. Example---the diameter of a circle is 20 cm. half the diameter is 10 cm, which is the radius. Multiply 2 times pi[which equals 3.14], times the radius. Good luck!
