Apulley 18 inches in diameter is driven by a belt at the rate of 90 revolutions per minute. what is the angular velocity of the pulley in radians per minute? what is the speed of the belt in feet per second?

90*2π，90/60*18/2

Step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

30005

yes ok
