Divide the diameter by 2.
Diameter = 2 x radius = 34 cm.
diameter times pi(3.14159) equals cicumference
circumference = π x diameter ⇒ diameter = circumference ÷ π = 32 in ÷ π ≈ 10.19 in
If 20 is the diameter, the circumference is 62.8 yards.

Divide the diameter by 2.
Diameter = 2 x radius = 34 cm.
C = ~53.41 cm
diameter times pi(3.14159) equals cicumference
circumference = π x diameter ⇒ diameter = circumference ÷ π = 32 in ÷ π ≈ 10.19 in
If 20 is the diameter, the circumference is 62.8 yards.
The cicumference of any circle divided by its diameter is aways equal to pi.
Cicumference = π*d = 56.55 units
pi=3.14 it is really long # but we shorten is to 3.14. 3.14 times the diameter
C=pi*diameter so your diameter equals 27 divided by pi, or about 8.59 ft
diameter. a radius doesn't even run through a circle. a circumference is the line that surrounds the circle.
