Circumference = pi x diameter. So the circumference of a circle with diameter 12 cm = pi x 12 = 37.7 cm (1 decimal place.)
circumference = diameter × π = 6π yards ≈ 18.85 yards
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.
24 meters.The diameter is twice the radius.Both radius and diameter are straight lines. The radius extends from the center of the circle to any point on the circumference. The diameter extends from any point on the circumference through the center to the circumference on the opposite side of the circle.
The circumference of a circle can be calculated using the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. In this case, the diameter is 12 inches. Plugging this into the formula, we get C = 3.14159 x 12 = 37.699 inches. Therefore, the circumference of a circle with a 12-inch diameter is approximately 37.699 inches.
