The answer for the question is option 2
1 2/7 = 9/7
9/7 * 6/7 = 54/49
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.
I would say B is the best choice.
