12mm - half the diameter.
The radius is half of the diameter, and 1/2 of 24 is 12. The radius is 12mm.
If the diameter is 12mm then the radius is 6mm. The area of a circle is pi X r2. Therefore pi X 36 mm2 = about 113.0973 mm2 = area of the circle. Don't forget units!! pi is about 3.1416.

1/2 of the diameter
12mm - half the diameter.
The radius is half of the diameter, and 1/2 of 24 is 12. The radius is 12mm.
If the diameter is 12mm then the radius is 6mm. The area of a circle is pi X r2. Therefore pi X 36 mm2 = about 113.0973 mm2 = area of the circle. Don't forget units!! pi is about 3.1416.
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.
A = 452.4mm2
Area of a circle = pi*r2 , where pi = 3.14 and r is the radius of the circle. We have diameter(d) = 12mm so, radius(r) = d/2 = 6mm On putting the values we get Area = 3.14*62 = 3.14*36 = 113mm2
The radius of a circle is half the diameter, so the radius of a 6 inch diameter circle is 3 in.
