A circle 14 inches in diameter has a radius of 7 inches, and a circle having a radius of 7 inches has a diameter of 14 inches.

7 inches, radius+1in=diameter. Always.

Radius = 1/2 of diameter = 7/2 = 3.5 inches

14 inches.

A circle's radius is always 1/2 of the circle's diameter, so the radius of a circle of 5-inch diameter is 2-1/2 inches.

A circle 14 inches in diameter has a radius of 7 inches, and a circle having a radius of 7 inches has a diameter of 14 inches.

7 inches, radius+1in=diameter. Always.

Its diameter: 2*3.5 = 7 inches

Radius = 1/2 of diameter = 7/2 = 3.5 inches

14 inches.

A circle's radius is always 1/2 of the circle's diameter, so the radius of a circle of 5-inch diameter is 2-1/2 inches.

7 inches.

14inches

The diameter of a circle is double the radius. So a circle with a radius of 7 cm has a diameter of 14 cm.

The circumference is about 43.98 inches. The circumference of a circle is diameter (radius x2) x pi (3.14).

The diameter of a circle is twice the radius. When the diameter is 7 metres, the radius is 3.5 metres.

It depends on what you mean by a "7-inch circle". If, as is normally the case, it is a circle with a 7-inch diameter, then you've got your answer in the question. If, unusually, you mean a circle with a 7-inch radius, then the diameter is twice that - 14 inches. If, even more unusually, you mean a circle with a circumference of 7 inches, then the diameter is 7/pi = 2.228 inches.
