What is the circumference of a circle with a diameter of 45 centimeters?
The formula to find Circumference is: C = Pi x D (Pi is 3.1416 and D is Diameter). Hence, 3.1416 x 45 = 141.372 cm Square centimeters (sq cm) are a measure of area. Circumference is measured in linear centimeters not square centimeters.
