Red ribbons are wrapped around all the columns of a building. each ribbon does not overlap itself. each column has a radius of 3 feet. if all the ribbons are taken off the columns and attached end to end, they would measure 144 pi feet long. how many columns does the building have? a)8 b)16 c)24 d)40 plzz

Hello!

If this long ribbon measures 144 feet, you can see, it was only multiplied by one number, which has the be the diameter of a column to get our circumference. If we divide this by our diameter 6 (diameter is double the radius, 3), we get our answer below.

144/6=24

Therefore, our answer is C) 24.

I hope this helps!

23, 11, -13

Step-by-step explanation:

y+6(-2)=11

y-12=11

y=23

y+6(0)=11

y+0=11

y=11

y+6(4)=11

y+24=11

y=-13
