The formula for the circumference of a circle is π x d (diameter).
Solution: C= π x d; C=3.1416 x 50; C=157.08 feet or 157 feet (rounded to nearest whole number).

Pi is the ratio of a circles circumfrance to its what?
diameter ------------- Diameter. The R (radius) of a circle multiplied by two equals the diameter.
How do you find out the circumfrance of a circle?
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!
What is the radius of a circle if the circumfrance is 31.4?
If the circumference (not circumfrance) is 31.4, the radius is 4.9975 units (to 4 dp).
How do you find the area circumfrance and the diameter of a circle?
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))
What is the diameter of a circle that is equal to pi?
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.
