The area of a circle is calculated from the formula Pi x r2 . A 1cm diameter circle has a radius of 0.5cm, thus it has an area of 0.785cm2
The radius will stay as 1cm but the area of a circle is: pi times radius squared
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 is half the diameter = 1cm

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.
The radius of a circle is half the diameter, so the radius of a 6 inch diameter circle is 3 in.
