diameter ------------- Diameter. The R (radius) of a circle multiplied by two equals the diameter.
To find the circumfrance of a circle, you need to multiply 2 times pi, times the circle's radius. If you don't know what that is, you multiply two times pi, and pi equals 3.14, and then multiply that by the radius, which is the measurement of half the circl'e diameter. the diameter is the distance from one side of the circle, to the exact opposite. you measure this with a ruler. HALF the measurement of the diameter is the radius. Example---the diameter of a circle is 20 cm. half the diameter is 10 cm, which is the radius. Multiply 2 times pi[which equals 3.14], times the radius. Good luck!
If the circumference (not circumfrance) is 31.4, the radius is 4.9975 units (to 4 dp).
Formula for area: A = Pi*R² (Pi = 3,1416 and R² is the radius multiplied by itself) Formula for circumference: C + Pi*D (D is diameter) Formula for Diameter: D = 2*R (radius multiplied by 2))
If you mean the diameter of a circle with area pi, then the diameter is 2. If you mean the diameter of a circle with circumference pi, then the diameter is 2. If you mean the diameter of a circle with diameter pi, then the diameter is pi. If you mean the diameter of a circle with radius pi, then the diameter is 2pi.
The diameter should be 7m.
In any circle, the ratio of circumference to diameter is (pi).
Diameter is the distance across a circle. The circumference of a circle is the distance around the outside of the circle.
circumference of a circle = pi*diameter or 2*pi*radius
Work it out the circumfrance of a circle is pie x the diameter!

3.9 x 3.14 m
Pi (3.14) × the diameter Therefore, 3.14 x 2 = 6.28 inches
Diameter. distasnce from center to edge is radius length around is circumfrance
26.5/pi = just under 8.5 inches
If you take pi as 22/7 the the circumference is 242 cm.
circumfrance= pi x diameterc= pi x 6c= 18.85
