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).

Find the circumference of the circle Use 3.14 and round to the nearest hundredth radius 47?

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.

What is circumference of circle with a radius of 1.75 inches?

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 #)

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 a wheel is 42 inches how long is the spoke?

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.
