For a circle of 20 feet diameter, its perimeter equals Pai x diam = 3.14 x 20 feet equals 62.80 feet around 63 feet.
A 20-inch diameter circle contains: 314.16 square inches.
314.159 ft2
The circumference of a circle can be calculated using the formula C = 2Οr, where C is the circumference, Ο is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. In this case, the radius is half of the diameter, so for a 20 ft circle, the radius would be 10 ft. Plugging this value into the formula, we get C = 2 x 3.14159 x 10 = 62.8318 ft. Therefore, approximately 62.83 feet would go around a 20 ft circle.
855.21 square feet. A circle with a radius 70 would be (pi)(radius squared) = (3.1416) (70) (70) = 15,393.8 square feet. With a 20 degree angle that is 20/360ths of a circle, so multiply your circle area by 20 and divide by 360 = 855.21 square feet.
The circumference of a circle = pi*diameter. 6 feet 3 inches = 6.25 feet, pi*6.25 = 19.63495408 feet or the circumference of the circle is nearly 20 feet.
If you mean how many feet AROUND the circle, that is the circumference. Multiply the diameter (3 feet) by pi- 3.14. About 9.42 feet

There are 20 linear feet across the diameter; and 20π ≈ 62.83 linear feet around the circumference.
how many linear feet in a 20 foot diameter
A 20-inch diameter circle contains: 314.16 square inches.
If the circumference of a circle is 20 feet the diameter is: 6.366 feet (circumference divided by pi = diameter).
314.159 ft2
circumference in feet = 20*pi
The circumference of a circle can be calculated using the formula C = 2Οr, where C is the circumference, Ο is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. In this case, the radius is half of the diameter, so for a 20 ft circle, the radius would be 10 ft. Plugging this value into the formula, we get C = 2 x 3.14159 x 10 = 62.8318 ft. Therefore, approximately 62.83 feet would go around a 20 ft circle.
Radius of a circle with 20' circumference = 20'/2pi = 3.18'Area of a circle with 3.18' radius = ((3.18')^2)pi = 31.8 square feet
Circumference of a circle = 2*pi*radius or pi*diameter Area of a circle = pi*radius squared
