pi is equal to the ration of the circumference to the diameter or c/d. For your equation we know 2 of the variables and can solve for the remaining one.
3.14 = c/25.8
3.14 * 25.8 = c
81.012 = c
The circumference is 81.012cm

Diameter = 314/pi feet
It's simple, just multiply de diameter of the circle by the pi number: 3.141592653.... the result is 31.14 cm, or 314 milimeters.
To find the diameter of a circle with a given area, you first need to calculate the radius using the formula for the area of a circle: A = πr^2. Given that the area is 314 cm^2, you can rearrange the formula to solve for the radius, which would be √(A/π). Plugging in the area, you get √(314/π) ≈ 10 cm. Finally, to find the diameter, you double the radius, resulting in a diameter of approximately 20 cm.
Approximatly 50inches
You have to use the equationcircumference is equal to the radius multiplied by "pi" multiplied by twoC = 2 * π * rBecause your circumference is a known value, the only unknown value left is the radius. Simply solve the equation.314 / (2*π) = rr = 50.0 feet
