The formula for the circumference of a circle = 2πr. Where r is the radius and thus the length of a spoke. When 42 = 2πr then r = 42 ÷ 2π = 6.6845 inches. The length of each spoke is 6.6845 inches (4dp).
Assuming a spoke represents the radius of the circle, each one would be 4.29 inches long. When given the circumference (27 inches), the radius (spokes) is calculated using the formula r = C / 2(pi); or Radius = 27 inches / [2(3.14)].
If this is a real-life question it can't be answered, as real rims and hubs have all kinds of shapes to them that mess up the measurements. IRL a spoke wouldn't reach all the way to the center for instance, it'd be attached some way off, at the hub flange. You'd also need to know what lace pattern is being used, as that affects spoke length. But if this was a maths question that isn't required to make sense then spoke length would be (42/pi)/2.
If by "27 inch wheel" you mean:"a wheel with a circumference of 27 inches" The answer is 27 inches."a wheel with a radius of 27 inches" The answer is 54π inches"a wheel with a diameter of 27 inches" The answer is 27π inches
Assuming what you're asking is for the circumference (distance around the entire wheel) the formula is r*2*pi. In this case the circumference is roughly 157 inches.
The formula for the circumference of a circle = 2πr. Where r is the radius and thus the length of a spoke. When 42 = 2πr then r = 42 ÷ 2π = 6.6845 inches. The length of each spoke is 6.6845 inches (4dp).
The spoke is the radius. Therefore 27/2pi is 4.297, the radius is rounded to 4.3 inches
Assuming a spoke represents the radius of the circle, each one would be 4.29 inches long. When given the circumference (27 inches), the radius (spokes) is calculated using the formula r = C / 2(pi); or Radius = 27 inches / [2(3.14)].
To determine the correct spoke length for your bicycle wheel, measure the distance from the hub flange to the rim hole where the spoke will attach. Use a spoke ruler or a measuring tape to get an accurate measurement. This measurement will help you choose the appropriate spoke length for your wheel.
To measure spoke length accurately for a bicycle wheel, you can use a spoke ruler or a spoke length calculator. First, determine the hub and rim measurements of your wheel. Then, input these measurements into the calculator or use the ruler to measure the distance from the hub to the rim hole. This will give you the correct spoke length needed for your wheel.

To calculate spoke length for a bicycle wheel, you need to measure the hub and rim dimensions, and then use an online spoke length calculator or a spoke length formula. These tools take into account factors such as the number of spokes, the lacing pattern, and the type of wheel.
We've already had this question. If this is about a real bike it can't be answered, as the spokes never go to the precise center of the wheel. If this is about maths, then basic geometry states that circumference = diameter times pi. A spoke would be the radius, which is half of the diameter. Pi is usually held at 3.14, but the numbers just keeps coming. Circumference / Pi = diameter Diameter / 2 = radius Now do the rest of the homework yourself.
To accurately measure spoke length for your bicycle wheel, you can use a spoke ruler or a spoke length calculator. Measure the distance from the inside of the hub flange to the top of the spoke hole, and then add the hub's flange diameter and the rim's effective rim diameter. This total will give you the correct spoke length needed for your wheel.
Circumference = 18*pi inches
To determine the spoke length for a bicycle wheel, you need to measure the hub and rim dimensions accurately. You can use an online spoke calculator or consult a bike shop for assistance in calculating the correct spoke length based on these measurements.
A wheel with a 26 inch diameter has a circumference of 81.68 inches. At 145 rpm a point on the circumference travels at 145*81.86 inches per min = 11843.8 inches per minute.
