Length of a radius is always half the diameter of a circle. This means that the circle has a radius of 2cm.

Area= pi*r2If the diameter of the circle is 2cm, the A= pi cm2If the radius of the circle is 2cm, then: A=3.14159*4=12.567 cm2

The area of a circle with a diameter of two cm is about 3.1416 cm.

The radius of the circle.

Since diameter is twice its radius, the radius of this circle would be 60

radius is half the diameter. so 4cm.

you half the diamater to get the radius, then you square the radius. Then you times it by 3.14. Always. example. Diameter=4cm then radius =2cm squared=4cm 4x3.14=12.56

The diameter of a circle is twice its radius

The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.

The diameter of a circle is twice its radius

The radius of a circle is always half of the diameter. If the diameter is 85.4, the radius is 42.7.

The radius of a circle is half of the diameter, so the radius of a circle with a diameter of 14in is 7in.
