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

Circumference of fitness ball with a 22 inch diameter?
Circumference = pi*d = 69 inches
What is diameter of 28 inch circumference?
To find the diameter of a circle with a circumference of 28 inches, we can use the formula C = πd, where C is the circumference and d is the diameter. Given that C = 28 inches, we can rearrange the formula to solve for d: d = C / π. Therefore, the diameter of a circle with a circumference of 28 inches is approximately 8.91 inches.

What is the circumference of a circle with a radius of 5 inches?
Q : What is the circumference of a circle with a radius of 5 inches ? Ans: The formula to calculate the circumference is 2 X Pie X radius. The value of radius is given as 5 inches. Substituting the value of r in the above formula then we get as the value of Pie is 22/7 = 2 X (22/7) X 5 = 220/7 = 31.41 sq. Inches. Also, Q: What is the circumference of a circle with a radius of 12inches?? A: The circumference is 75.366 inches, because the formula is 2 x Pie x r
