You can use the circumference of the pencil and the circumference formula to find the radius. Set the measured circumference equal to 2pi*radius and solve. I measured it to about .75 of an inch, so: .75=2pi*radius r=.75/2pi
Circumference = 2*pi*r Circumference = 2 *pi*12 mm 75 mm =====
75cm = 29.53"
11.93662073 inches
23.87 inches.
If the circumference of a circle is 75 inches, the diameter is: about 23.87 inches. (diameter = circumference divided by pi).
The cricle's circumference is a linear function of its radius, so they change in direct proportion.If the radius increases by 75%, the circumference also increases by 75%.

If the circumference of a circle is 75 feet, the diameter will be 23.87 feet. (d = c divided by Pi).

48 works out as a circumference of 24.5597207 units 75 works out as a circumference of 30.69980124 units So the ratio is about 4:5
The diameter of this size tire is 24.9 inches and the circumference is 78.3 inches.
