Question

the spoke of a wheel reaches from the center of the wheel to its rim. If the circumstances of the rim of the wheel is 42 inches, how long is each spoke?

Answer 1

The spoke of the wheel serves as the radius of the circle.
To solve for the circumference of the circle, we use this formula:

C = 2πr
42 inches = 2 * 3.14 * r
42 inches = 6.28 * r
42 inches / 6.28 = r
6.69 inches = r

The length of each spoke is 6.69 inches.
