The circumference of a circle is the product of pi and the diameter. If d represents the diameter, d X pi = 50 cm or d = 50/pi = 16, to the justified number of significant digits.
Diameter = circumference / PI = 50cm/3.1415 = 15.92cm
In any circle, the ratio of circumference to diameter is (pi).

Circumference = 2*pi*radius or diameter*pi
10/pi = 3.1831 feet (rounded)
The diameter should be 7m.
Diameter = circumference / PI = 50cm/3.1415 = 15.92cm
Here are the three circle equations, in words and equations. Circumfwerence - pi X diameter C = pi d Circumference = two X pi X radius C = 2pi r Area = pi X radius squared A = pi r^(2) NB It is only the radial value that is squared ; NOT 'pi'. NB pi is a constant at 3.141592..., usually approximated to 3.14 or 3.1416.
In any circle, the ratio of circumference to diameter is (pi).
Divide the circumference by pi.

diameter ------------- Diameter. The R (radius) of a circle multiplied by two equals the diameter.
circumference of a circle = pi*diameter or 2*pi*radius
Circumference = 2*pi*radius or diameter*pi
10/pi = 3.1831 feet (rounded)
