The ratio is 1 : 1 since the two measures are equivalent.
A circle with a 12 inch diameter has a 6 inch radius.
12 inch diameter(also 6 inch radius).
6 inch, because the radius the basically half of the diameter
12 inch diameter(also 6 inch radius).
6 inches
6 inches because the 12-inch softball would be the diameter.
I assume 12 is diameter. If so 12/2 is radius of 6in. 6x6xpi is 113.1squared inches
Diameter of a circle is defined as twice the radius. So if diameter is 12, the radius is 6.
If the diameter is 12 cm the radius is 6 cm.
The radius of a circle is one-half of the circle's diameter. So if the radius is 12 inches, the diameter is 24 inches.
12 ft. The radius is half of the diameter.
radius = diameter ÷ 2 = 12 ÷ 2 = 6 units.
