Remember for circle equations.
C = 2 pi r
Algebraically rearrange
r = C / ( 2 pi)
Substitute
r = 52 / ( 3.1416 x 2)
Cancel down by '2'
r = 26/ 3.1416
r = 8.27605...
r = 8.28 ( To nearest hundredth).
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
To calculate the circumference of a circle, you can use the formula ( C = 2\pi r ), where ( r ) is the radius. Without the radius provided, I can't give a specific numerical answer. However, if you have the radius, simply substitute it into the formula and round the result to the nearest tenth. If the diameter is known instead, use the formula ( C = \pi d ).

52 pt * (2 c / 1 pt) = 104 c
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
To calculate the circumference of a circle, you can use the formula ( C = 2\pi r ), where ( r ) is the radius. Without the radius provided, I can't give a specific numerical answer. However, if you have the radius, simply substitute it into the formula and round the result to the nearest tenth. If the diameter is known instead, use the formula ( C = \pi d ).
For circumference, multiply the diameter by pi and round the product to the second decimal place. For area, multiply the square of the radius by pi and round the product to the second decimal place.
