A wheel with a radius of 7 inches is rotating at 4 revolutions per second. What is the linear speed v, in feet per second

Linear speed= V= 175.84 m/s

Step-by-step explanation:

A wheel with a radius of 7 inches is rotating at 4 revolutions per second.

Linear speed v = rw

r= radius

r= 7 inches

w= angular speed

W= 4rev/s

But one rev= 2π

W= 4*(2π)/s

W= 8π/s

V= rw

V=7*8*3.14

V= 175.84 m/s

it has 4
