How many square feet in 20 inch diameter circle?
A 20-inch diameter circle contains: 314.16 square inches.
How many square feet are in a 20 foot diameter circle?
314.159 ft2
How many feet go around a 20 ft circle?
The circumference of a circle can be calculated using the formula C = 2πr, where C is the circumference, π 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.
Area of an arch of circle with a radius of 70 feet The angle of the arch is 20 degrees?
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 diameter of a circle is 6 feet 3 inches what is the circumference of the circle?
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.
