What is the radius of a circle of a circumference of 121?

To find the radius of a circle with a circumference of 121, you can use the formula for the circumference of a circle: C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 121, you can plug this value into the formula and solve for the radius. Dividing 121 by 2π will give you the radius of the circle, which is approximately 19.24 units.

What is the circumference of a circle with a radius of 5 yards?

The circumference is Pi x Diameter. The radius is half the diameter. So the circumference is also 2 x Pi x Radius. Pi= 3.14159 Radius is given as 5 yards. So the circumference is 31.459 yards or 94.377 feet or 1132.5 inches.

What is the radius of a circle with a circumference of 20 inches?

To find the radius of a circle with a circumference of 20 inches, you can use the formula for circumference: C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 20 inches, you can plug this value into the formula: 20 = 2πr. Solving for r, you get r = 20 / (2π) ≈ 3.183 inches. Therefore, the radius of the circle is approximately 3.183 inches.
