You multiply the diameter by Pi, that is 3.14159 (to the nearest 5th decimal). circumf. = dia. x Pi.
In any circle, the ratio of circumference to diameter is (pi).
Circumference = 2*pi*radius or diameter*pi
3.9 x 3.14 m
10/pi = 3.1831 feet (rounded)
circumference of a circle = pi*diameter or 2*pi*radius
The diameter should be 7m.

Divide the circumference by pi.
yes
diameter ------------- Diameter. The R (radius) of a circle multiplied by two equals the diameter.
Circumference = 2*pi*radius or diameter*pi
To find the circumference of a circle, you have to multiply Pi and the Diameter. This means that to work out the answer you multiply Pi by 1.25. This equals 3.92699081, which rounded equals 3.93 (2dp) - the circumference of a circle with a 1.25 diameter.
3.9 x 3.14 m
10/pi = 3.1831 feet (rounded)
Diameter is the distance across a circle. The circumference of a circle is the distance around the outside of the circle.
