A circle with a 12 inch diameter has a 6 inch radius.
The radius of a circle is half the diameter, so the radius of a 6 inch diameter circle is 3 in.
The Diameter of a Circle is twice the Radius.thus for a 52 inch Diameter Circle the Radius will be 52/2=26 inches.
2 inches. the radius is half of the diameter
6 inches.
11.5 inches for a 23-inch diameter circle. If you meant the circumference is 23 inches, then the radius would be 3.6606 inches.
It is customary to call a circle a 38 inch circle if its diameter is 38 inches. If that is the case, the radius = diameter/2 = 19 inches.
Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.
The radius is half of the diameter. So, if the radius is 7 the diameter is 14.
d = 2r, where d is diameter and r is radius.
12 inch diameter(also 6 inch radius).
Radius of the circle: 3.65/2 = 1.825 inches
