the diameter would be 7 inches
14 inches in diameter
Diameter = 1.273 inches.
The circumference of a circle, if the diameter is 9.5 inches, is: 29.85 inches (diameter x Pi = circumference)
Circumference = (pi) x (diameter) = 14 pi = 43.9823 inches (rounded)
39 inches / pi = 12.4 inches
The circumferance is found by using the formula 2(r)(pi). r stands for the radius. The diameter, which is already given in the problem, is two time radius. Therefore the only thing you really have to do is multiple the diameter= 3 inches by pi. Circumferance is 9.425 inches.
Circumference = Pi x diameter Pi = 3.14159 so the circumference = 3.14159 x 1 =3.14159 inches
circumference/pi = diameter
Circumference of a circle is pi times diameter therefore C = pi(3.14159265359) * 6 = 18.84955592154 say 18.85 inches (3.14159265359 is the approximate value of pi)

circumference = pi*100mm
divide the circumference by 3.14 to get the diameter - then divide that by 1/2 to get the radius Radius = Circumference / 2 x pi from C = Diameter x pi
circumference = pi*diameter so diameter = circumference/pi = 19.1 metres.
If the diameter is known, don't bother measuring the circumference.Simply multiply the diameter by 'pi'.
Either pi times the diameter or pi times twice the radius (which is the diameter)
