Need help in number 19. Thanks for helping
Fudgin [204]

Answer:

D

Step-by-step explanation:

Volume of a cylinder is equal to the area of the base circle times the height of the cylinder.

The area of your base circle is \pi r^2 where r=15 and they are using \pi as 3.14.

So we have the area of your base circle is 3.14 \cdot 15^2=706.5 inches squared.

Now to find the volume of a cylinder again you just multiply your base area by your cylinder and you get:

40 \cot 706.5=28260 cubic inches

6 = 2(y + 2)<br> Solve for y
egoroff_w [7]
Awnser: y=1
Distribute
6=2(y+2)
6=2y+4
subtract 4 from both sides of the equation
6=2y+4
6-4=2y+4-4
simply
2=2y
then divide 2 from both sides
2/2=2y/2
y=1
Hope this helps :)
