Question

A wheel with a 24-inch diameter is turning at the rate of 32 revolutions per minute. To the nearest inch per minute, what is the linear velocity of a point on the rim?

Answer 1

one circumference = 2π(12) = 24π inches
in one minute it covers 32(24π) or 768π inches

so the linear velocity is 768π inches/min
= appr 2413 inches/min

Answer 2

12*32*2pi = 2413

cool.

thank you
