Well, honey, if the circumference of a circle is 77cm, then we can use the formula C = 2πr to solve for the radius. Plug in 77 for C, divide by 2π, and you'll find that the radius is approximately 12.25cm. So there you have it, darling, the radius of that circle is 12.25cm.

To find the radius of a circle when given the circumference, you use the formula C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 77cm, you can plug this value into the formula: 77 = 2πr. To solve for r, divide both sides by 2π, which gives you r = 77 / (2π) ≈ 12.25 cm. Therefore, the radius of the circle is approximately 12.25 cm.
