The diameter should be 7m.
Diameter. distasnce from center to edge is radius length around is circumfrance
To find the circumference of a circle, you have to multiply Pi and the Diameter. This means that to work out the answer you multiply Pi by 1.25. This equals 3.92699081, which rounded equals 3.93 (2dp) - the circumference of a circle with a 1.25 diameter.
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.
First you have to know the distance you wish to travel. Then you simply calculate the circumfrance of the tire. (2pie*radius) which would give you around 4.77 inches. Divide the distance you want to go by 4.77 and you get the proper amount of turns.
The diameter should be 7m.
In any circle, the ratio of circumference to diameter is (pi).
yes

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
Based on what? You can measure it. Or, for example, if you know the diameter, you can divide that by 2.
3.9 x 3.14 m
10/pi = 3.1831 feet (rounded)
Diameter is the distance across a circle. The circumference of a circle is the distance around the outside of the circle.
Pi (3.14) × the diameter Therefore, 3.14 x 2 = 6.28 inches
