The radius of a 2 cm circle is: 1 cm
The radius (radii) of a circle is 1/2 of the diameter. The radius of a circle with a 6.2 cm diameter is 3.1 cm.
The circumference of a circle if the if the radius is 6 cm is: 37.7 cm
4 cm radius = Area of 50.26548 sq. cm.
A circle with a radius of 13.8 cm has a circumference of 86.71 cm.
This indicates a radius of 4 cm, in which case the area of the circle is: 50.27 square cm
Well, honey, if you want the radius of a circle with a 58 cm circumference, you just divide that by 2π, which gives you approximately 9.22 cm. So, there you have it, darling, the radius of that circle is about 9.22 cm.
The formula is: A = PI(r)^2 A circle with a radius of 29 cm has an area of 2,642.08 square cm.
If it is a 7.1 cm radius circle, then its radius is exactly 7.1 cm!
The radius of the circle is: 9.549 cm
The radius of a 2 cm circle is: 1 cm
A=Pi(r)2 - A circle with a radius of 4 cm has an area of 50.27 square cm
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm
If a circle has a circumference of 16 cm then the radius is about: 2.546 cm
14 cm. The diameter is just the radius times 2.
They're equal, 12 cm long.
If the diameter is 12 cm the radius is 6 cm.
