C= pi x 2 x radius or C= pi x diameter. Remember, diameter is 2 x the radius, so: C= 3.14 x 2 x 1.75 or C= 3.14 x 3.5 C= 10.99(or 11 rounded to the nearest whole #)
If r = 13 inches then C = 81.7 inches

52 pt * (2 c / 1 pt) = 104 c
Remember the general equation for a circle. C = 2pi r Algebraically rearrange r = C / (2 pi) Ehere C = 42.1 pi = 3.141592.... Constan '2' Substitute. C = 42.1 / ( 2*3.141592....) C = 6.7 units (nearest tenth).
Circumference = pi * 2 * r C = 3.14 * 2 * 47 = 295.16

First off 42" is a very weird size for a bike wheel. Secondly, there's no way of telling. To be able to tell you need to know how high the hub flanges are, what the rim looks like in cross section and what pattern the spokes are laced in.
The circumference of a circle with radius of 7 km is 44.0 km (to the nearest tenth), and the area of a circle with radius of 7 km is 153.9 km (to the nearest tenth).C = 2 pi RA = pi R2
If r = 13 inches then C = 81.7 inches
If the circumference of a circle is 7 cm, the radius is 1.114085 cm, which rounds to 1.1 cm

To round off to the nearest integer... double a = {some value}; a = (int) (a + 0.5); To round off to the nearest hundredth... double a = {some value}; a = (int) (a * 100. + 0.5) / 100.; These are just two examples.
