12 inch
The area of a circle is calculated using the formula A = πr^2, where r is the radius of the circle. For a 12-inch circle, the radius is half of the diameter, so the radius is 6 inches. Therefore, the area of the 12-inch circle is A = π(6)^2 = 36π square inches. Similarly, for a 9-inch circle, the radius is 4.5 inches, so the area of the 9-inch circle is A = π(4.5)^2 = 20.25π square inches.
Its radius will be 76/2*pi which is about 12 inches rounded to the nearest integer
2 inches. the radius is half of the diameter
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.
A circle with a 12 inch diameter has a 6 inch radius.
12 inch
6 inch, because the radius the basically half of the diameter
6 inches
12 inch diameter(also 6 inch radius).
The radius (not raduis) is 6 inches.

12 inch diameter(also 6 inch radius).
I assume 12 is diameter. If so 12/2 is radius of 6in. 6x6xpi is 113.1squared inches
The radius of a circle with a 14.5 inch circumference is 2.15 inches
Circumference of a circle = 2*pi*radius or pi*diameter
A 12-inch circle has an area of 0.784 square feet.
