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
The formula for circumference is C = Pi x D where Pi = 3.1416 and D is the diamter. The radius is one-half of the diameter. You can find the radius by applying the formula for circumference and solving for D, then dividing by 2: 42.1 = 3.1416 x D 42.1 ÷ 3.1416 = D 13.4008 = D D ÷ 2 = R 13.4008 ÷ 2 = R 6.7 = R
The circumference of a circle can be calculated using the formula C = 2πr, where r is the radius. Given the radius as 47, the circumference would be C = 2 * 3.14 * 47 = 294.04. Rounding to the nearest hundredth, the circumference is approximately 294.04 units.

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
