Answer:

  • 30,631 inches
  • 2553 feet

Step-by-step explanation:

The length of one revolution of the sprocket is ...

  C = 2πr = 2π(1.5 in) = 3π in

Then the length of 3250 revolutions is ...

  3250(3π in) = 30,630.53 in

About 30,631 inches of chain travel past the sprocket in one minute.

__

There are 12 inches in a foot, so the number of feet is ...

  30,630.53 in/(12 in/ft) = 2552.54 ft

About 2553 feet of chain travel past in one minute.

Circle the volume in cm^3 of a cylinder with the radius 5cm and height 8cm
Phantasy [73]

Answer:

<em>628 </em>cm^{3}

Step-by-step explanation:

Since the formula to find the volume of a cylinder is \pi r^{2}h, we just need to fill things in.

Since the radius is 5 and the height is 8 and we know that pi=3.14, our new equation is:

3.14*5^2*8.

5*5=25. Now we simplify.

3.14 * 25 * 8

78.5 * 8

<em>628 </em>cm^{3}

Hope this helps!! <3 :)
