Best Answer

The circumference of a circle equals the diameter times pi. The diameter is two times the radius.

So a circle with a radius of 6 would have a diameter of 12, and a circumference of 12pi.

The circumference of a circle is 2*pi*r. With r = 3, the circumference is 6 pi.

6 inches because the diameter is twice the radius 3+3 = 6 circumference = pi*6 = 18.849 inches

A circle with a radius of 6 mm has a circumference of 37.7 mm

The circumference of a 6 inch diameter circle is: 18.8 inches. (diameter x Pi = circumference)

It needs to be more specific. is 6 the diameter or radius of a circle?

A circle with a radius of 6 inches has a circumference of 37.7 inches.

Circumference = 2*pi*6 inches

Diameter = 6 inches Radius = 3 inches Circumference = 2 x pi x radius = 18.84955592 inches

Circumference of a circle: 2*pi*radius or pi*diameter

The circumference of a circle is 2*pi*r. With r = 3, the circumference is 6 pi.

6 inches because the diameter is twice the radius 3+3 = 6 circumference = pi*6 = 18.849 inches

12π or approximately 37.699 inches

well the circumference of a circle is the perimeter so the formula is 2**r or *d so 2*3.14*6= 37.68 inches

Circumference: 2*pi*3 = 6*pi inches

A circle with radius of 3 inches doesn't have a diameter of 10 inches. If the radius is 3, then the diameter is 6, and the circumference is (6 pi) = 18.85 . (rounded) If the diameter is 10, then the radius is 5, and the circumference is (10 pi) = 31.42 . (rounded) The diameter is always double the radius, and the radius is always half of the diameter.
