Thanks for your answer!

The formula for the volume of a cylinder is

V= π*r^{2}*h

We can now just input the height and raidus into the equation.

V= π*(19)^{2}*18

V= π*6498

V ~=~ 20403.72

The volume of the cylinder is approx. 20403.72 feet.

So to start, lets take the blank space as x.

13*5*13x*3=13*17

Next, lets simplify the equation

2535x=221

dividing 2535 by both sides we now get

x=221/2535

This can be simplifed to be

x= 17/195.

17/195 is the answer.

-(-2+2) = -14

2 - 2 = -14

0 = -14

0 does not equal negative 14.

Therefore, the equation is false.

So the rate that your 20 members work at is 6000/24, which is 250 square feet per minute.

9000/250 = 36 minutes.

It would take 20 members 36 minutes to paint a 9000 square foot wall.
