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.
12 inch
2 inches. the radius is half of the diameter
6 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.
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.
12 inch diameter(also 6 inch radius).
12 inch diameter(also 6 inch radius).
A circle with a 12 inch diameter has a 6 inch radius.
The radius of a circle with a 14.5 inch circumference is 2.15 inches
38: the diameter of a circle is twice its radius.
A four-inch radius circle has an area of about 50.27 square inches.
If the circumference is 38, the diameter is 38/pi. Since the radius is half of the diameter, the radius is 19/pi.
12 inch
1 inch
The radius of a circle is half the diameter, so the radius of a 6 inch diameter circle is 3 in.
The radius is one-half of the diameter. Hence, the radius of a 76 in diameter circle is 38 in.
radius of 31 inches
