Circumference = 18*pi inches
Circumference of circle: 5.5 times pi
diamiter X pi( 3.14...) in this case aprx. 21
Circumference of the circle = 7*pi feet
Multiply the diameter by 3.14 (pi).
since the equation to get circumference is diamiter X pi, and the diamiter is 2x the radius, yes it would double the C of the circle ie before radius is 2, so diamiter is 4 4 X Pi 12.57... radius is 4 so the diamiter is 8 8 X pi = 25.13... that would double it.
circumference = diameter × π → diameter = circumference ÷ π Circumference of tyre = distance/rotations = 1320 ft / 180 = 7 1/3 ft → diameter = 7 1/3 ft ÷ π ≈ 2.33 ft
Circumference = π*d = 7π = 21.99 ft
circumference = diamiter times pie 3.14 times 10 move the decimal over once its 31.4
7 1/2 inches (in diamiter) for my AAA little game ball
well you can divide the circumference by pi (3.14) and it will always give you the diameter or you could measure it.
