If its the diameter you have, then take pi as 3, multiply by the diameter, in this case 3 * 9 = 27 feet circumference approx.
35 feet.
100.53 feet.
A circle with a diameter of 9 feet has a circumference of about: 28.27 feet (diameter x Pi = circumference).
The approximate circumference of a circle can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. If the diameter is 70 feet, then the circumference would be ( C = \pi \times 70 ), which is approximately 219.91 feet. If 70 feet refers to the circumference itself, then it is simply 70 feet.

Assuming 30 feet is the diameter, its 94.2ft
Circumference is simply pi times the diameter. The approximate value of pi is 3.14, so for a circle 4 feet in diameter, the circumference is 4 x 3.14 = 12.56 feet, approximately.
