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

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

Half it and so 22/2 = a radius of 11 inches
What is the radius in inches if the circumference is 22?
22 = 2 x pi x r 11 = pi x r r = 11/3.1415 = 3.501 inches
What is the radius of a circle with a circumference of 22?
The radius is 3.5
How do you find the circumference of a circle if the radius is 11 inches?
Multiply the radius by 2 to get the diameter, then diameter times pi to get the circumference.C = (pi) D = (pi) 2rC = (3.1416) x [2 x 11] = (3.1416) x 22 = about 69.1 inches
