Circumference (the number I assume you want) = Pi X D
C = 3.14 x 30

how many linear feet in a 20 foot diameter
43 linear feet. The diameter of the circle is the longest distance that you can have in the circle.
The circumference of a 12-foot-diameter circle is 37.7 feet.
None. A 12 foot diameter is the length across a circle: it is a linear distance, not an area.
Circumference of a circle = 2*pi*radius or pi*diameter Area of a circle = pi*radius squared
