Answer:

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

How do i solve this equation? and could you show it to me step by step?
ipn [44]
The answer is 8 and yea it’s 2 steps first u have to remove the constant so u subtract 74-2=72 and 2-2=0. After u get rid of the constant u divide both sides by 9 basically 72/9 and 9/9 which is 8. So n is equal to 8 I hope this helped. I know it can be confusing
