Find the diameter of a circle if the radius is:
5.5cm
Diameter of the circle is twice the radius of the circle.
d=2r
Given radius of a circle, r=5.5cm
Diameter of a circle, d=2r=2×5.5cm=11cm
Hence, diameter of a circle is 11cm if the radius is 5.5cm.
Find the radius of a circle if the diameter is 21cm
Find the radius of the circle if the diameter is:
6cm
If the diameter of the circle is 12cm, find the radius of the circle.
