What is the radius if the circumference is 12 inches?

Answer 1

Well, darling, if the circumference is 12 inches, we can use the formula Circumference = 2 * π * radius. So, 12 = 2 * π * radius. Solve for radius, and you'll get radius = 12 / (2 * π) ≈ 1.91 inches. So, there you have it, sugar, the radius is approximately 1.91 inches.

Answer 2

The radius and circumference of a circle are related as C=2*pi*R (* stands for multiplication) where C is the circumference(=12 inches in the given case), R is the radius(to be found out) and 'pi' is a constant whose value is approximately 3.141592654. To find R the formula becomes R=C/(2*pi). Substituting 12 inches for C and the value of 'pi' we arrive at the following result:

R or radius=12/(2*3.141592654)=1.909859317 inches.
