How do you find the radius with a circumference of 22 inches? - Answers

Circumference = 2 x π x radius ⇒ radius = circumference ÷ (2 x π) So divide the circumference by 2 x π ~= 2 x 3.14 = 6.28 ⇒ radius = 22 inches ÷ 6.28 ~= 3.5 inches. As an approximation to π (the ratio between a circle's circumference and its diameter), the value 22/7 is sometimes used (to 2 decimal places 22/7 = 3.14 & π = 3.14). The circumference given as 22 inches suggests this approximation should be used: 22 ÷ (2 x 22/7) = 22 x 7/22 ÷ 2 = 7 ÷ 2 = 3.5
