The radius would be 4, because the radius is always half of the diameter.

3 feet

The radius is 1.5. The formula to get the radius is Diameter/2.

Arch length, or linear distance of an arch, is equal to: (Angle of Arch in Radians) x (Radius of Arch) So for a complete circle (Arch angle of 360 Degrees) with a diameter of 3 feet (or radius of 1.5 feet) the linear circumference would be: (2 x PI) x (radius) = (2 x PI) x (1.5 ft), where PI = 3.14 radians and represents 1/2 of a complete circle. This is also the equation for a circle's circumference.

Your questions is not solvable the way you wrote it. If you mean, "What is the radius of a circle with a diameter or 6 feet?" , then the answer is 3 feet. Reason is because the radius of a circle is half of its diameter.

6 ft

A circle with a radius of 3 feet has a circumference of 18.85 feet.

The radius would be 4, because the radius is always half of the diameter.

-- 3 feet in the diameter -- 1.5 feet in the radius -- 9.425 feet in the circumference (rounded)

Diameter = Radius*2 So radius = 3 feet

If 6 feet 6 inches is its diameter then its radius is 3 feet 3 inches

3 feet

3 feet(im sure.....i think.....)

The radius of a circle is half the diameter, so the radius of a 6 inch diameter circle is 3 in.

diameter is 3 ft diameter = 2*radius diameter/2 = radius 3/2 = 1.5 ft = radius area is pi * radius2 3.14 * (1.5)2 3.14 * 2.25 = 7.065 sq ft

The radius of the circle is 1.5 units and the diameter is 3 units.
