Step-by-step explanation:

Volume of a cylinder=pi*r^2*h

Radius=8/2=4

Height=12

Volume=603.19

Volume of a cone=pi*r^2*(h/3)

radius=8/2=4

Hight=16-12=4

Volume=67.02

603.19+67.02=670.21ft^3

Help please!!!

y varies directly with x.

The constant of variation is k = 7

Step-by-step explanation:

We have to check whether both vary directly with each other or not.

Every pair of x and y will be considered one by one

If y varies directly with x, it should satisfy y = kx or k = yx

So,

For x= -2, y=-14

-14 = -2k\\k = \frac{-14}{-2}\\k = 7

For

x=3, y=21

21 = 3k\\ k = \frac{21}{3}\\k = 7

For

x=5, y=35

35 = 5k\\ k = \frac{35}{5}\\k = 7

As k is same for all pairs of x and y, it can be concluded that:

y varies directly with x.

The constant of variation is k = 7
