Diameter Radius

Diameter Radius To find the circumference using the diameter you multiply Pi (3.14) By the diameter

Diameter Radius 7 First we will put in a number where the word ‘diameter’ was. Then you multiply the diameter (7) By pi (3.14) 3.14 x 7 = 21.98So your circumference is

Diameter Radius To find the circumference using the radius you multiply Pi times the radius times Itself. (Or 2 x Pi x Radius)

Diameter Radius First we will put the number 3.5 In where the word ‘radius’ is. 3.5 Then you multiply your radius by pi by x 3.14 x

Okay so you learned how to Find the circumference Using the diameter and Using the radius. Formulas Pi x diameter Pi x radius x 2
