The circumference of a circle is equal to 2 x pi x radius, where "pi" is approximately 3.1416.
The radius is equal to 1/2 the diameter. 11 divided by 2 =5.5
If it is a 7.1 cm radius circle, then its radius is exactly 7.1 cm!
Area of a circle with radius r is pi*r2 where pi is the irrational number approximately equal to 3.14159. You now have all the information required to answer this and other similar questions.
Approximately 50.26m, because circumference is equal to diameter times pi (or 3.1415). Or twice the radius times pi.
No, the radius of a circle is always 1/2 of the diameter.
Yes. The radius of a circle is the distance from the centre of the circle to every point on its circumference.
The radius of a circle is the distance from the center of the circle, out to the edge of the circle. The distance all the way across the circle is the "diameter." Half of the diameter is the radius.
Circle with a radius of 8 feet equals a circle with a diameter of 16 feet.
The circumference of a circle with radius 30 is equal to 2 times the radius times pi, or about 188.5.
the radius of the circle is 2 units
A unit circle is a circle with radius equal to one.
The radius is 18.
A circle with a radius of 1 unit has an area of 3.14 square units.
