The radius is double the diameter so 4cm.
2cm; the diameter of a circle is twice its radius.

Diameter of circle = 2 * Radius of the circle.
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 diameter of a circle is twice the radius. Since the radius of the 2 cm circle is 2 cm, the diameter is 2 x 2 cm, which equals 4 cm. Therefore, the diameter of the 2 cm circle is 4 cm.
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 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.
The radius of a circle is half the diameter, so the radius of a 6 inch diameter circle is 3 in.
The radius is half of the diameter of a circle
