If a circle has a circumference of 6 inches the diameter is: 1.91 inches (circumference divided by Pi = diameter).
Since circumference equals pi times the diameter, if the diameter of a circle is 6, then its circumference is going to be pi times 6 or 6 pi.
If a circle has a circumference of six feet its diameter is 1.91 feet.
The circumference of a 6 foot diameter circle is: 18.8 feet. (C = d x Pi)
They would have to give you enough information to eventually get the diameter. If they gave you the area of a circle and asked for the circumference, you can determine the radius, and from the radius the diameter, and then the circumference. If they said "What is the circumference if the area of a circle is 36pi?" Area of a circle is pi*r2, which would give us a value for r = 6 Diameter is 2*r, or = 12. Circumference is d*pi, or 12pi
The circumference of a circle if the if the radius is 6 cm is: 37.7 cm
circumference = 6*pi cm
Circumference of the circle: 2*pi*6 = 37.699 cm to three decimal places
18.85 cm
Circumference: 2*pi*6 = 12*pi cm
circumference = π x diameter = 6π cm ≈ 6 x 3.142 cm ≈ 18.85 cm
The answer depends on what measurement the 6 cm refers to: the diameter? circumference?
C = ~37.7 cm
18.84
Circumference of the circle: 2*pi*6 = 37.699 cm rounded to 3 decimal places
18.8496 cm. Just multiply your diameter by pi.
The circumference of the small circle would be 18.84.
