Answer:

11860.22 rev/hour

Step-by-step explanation:

The diameter if a cylinder, d = 21.02 inches

Radius, r = 10.51  inches

or

r = 0.875 feet

The linear speed of a point on the cylinder's surface is 18.12 ft/sec.

We need to find the angular speed of the cylinder.

The relation between the linear speed and the angular speed is given by :

v=r\omega

Where

\omega is angular speed

\omega=\dfrac{v}{r}\\\\\omega=\dfrac{18.12}{0.875}\\\\\omega=20.7\ rad/s

or

\omega=11860.22\ rev/hour

So, the required angular speed of the cylinder is 11860.22 rev/hour.

( 6 − √ 100 − 6 ⋅ 6 ) 3 − 9 ÷ 3
sergij07 [2.7K]

Answer:

(6 - √ 100 - 6 * 6) 3 - 9 ÷ 3 = -64003/1 = -64003

Step-by-step explanation:

1.Square root: sqrt(100) = √ 100 = 10

2.Subtract: 6 - the result of step No. 1 = 6 - 10 = -4

3.Multiple: 6 * 6 = 36

4.Subtract: the result of step No. 2 - the result of step No. 3 = -4 - 36 = -40

5.Exponentiation: the result of step No. 4 ^ 3 = (-40) ^ 3 = -64000

6.Divide: 9 / 3 = 3

7.Subtract: the result of step No. 5 - the result of step No. 6 = -64000 - 3 = -64003
