By outside distance, do you mean the circumference? The circle has a diameter of 16ft, its circumference is 3.14*16=50.24ft
Circumference of the circular pool: 20*pi feet
Circumference is pi times diameter. Diameter is circumference divided by pi. Diameter is twice the radius. Radius is half the diameter.
Diameter = Circumference/pi
Since the circumference is Pi times the diameter then divide the circumference by Pi (3.14159) to get the diameter
By outside distance, do you mean the circumference? The circle has a diameter of 16ft, its circumference is 3.14*16=50.24ft
The circumference of a 27-foot diameter circle is about 84.82 feet. (diameter x Pi = circumference).
Six feet. Circumference = 2PiR, or Pi * Diameter. Pi is close to 3, so a pool with circumference of 18' would have a diameter of 6'
If the diameter is 25 feet then the circumference is 78.5 feet (approx).
The diameter of a pool ball is 2 and 1/4 inch diameter. The radius of a pool ball is 1 and 1/8 inches. The radius is one half of the diameter.
Circumference of any circle = 2*pi*radius or diameter*pi
Circumference of a circle = (pi) x (diameter)C = (22) x (pi) = 69.115 feet (rounded)
Circumference of pool ball: 2*pi = 6.283 inches rounded to 3 decimal places
Circumference of the circular pool: 20*pi feet
Divide the circumference by (2 x pi).
484/7 = 69 and one seventh ft
approx. 6.28 in.
