Question

A bicycle wheel with radius 26" rotates through an arc that measures 80°. What is the length of the arc of the tire that touched the ground?

a. 2.88 pi inches
b. 5.78 pi inches
c. 11.56 pi inches

Answer 1

Arc = (degree/360)* circumference

Answer 2

Arc Length=\[\frac{ x }{ 360 }*2pir\]

Answer 3

If x = 80, and r = 26,
then Arc length = (x/360) . 2pi.r = (80/360).2pi(26) = ....

Answer 4

I got 5.78 pi
