2Ï€r = 122
since π≈3, r≈20
Estimate the radius of the object. Round to the nearest hundredth if necessary. An object has a circumference of 122 in. What is the radius in inches?

To find the radius of an object given its circumference, you can use the formula:
Circumference = 2 * π * radius
In this case, the circumference is given as 122 inches. Rearranging the formula to solve for the radius:
radius = Circumference / (2 * π)
Substituting the given value:
radius = 122 in / (2 * 3.14)
Simplifying this calculation:
radius ≈ 19.39 in
Therefore, the estimated radius of the object is approximately 19.39 inches.
