The cone has a height of 9 in and a diameter of 6 in. Find the volume of the popcorn container. Use 3.14 for π

Keith_Richards [23]

Answer:

The volume of the popcorn container is $V=84.78\ in^3$

Step-by-step explanation:

we know that

The volume of the cone is equal to

$V=\frac{1}{3}\pi r^{2}h$

where

r is the radius of the base of cone

h is the height of the cone

In this problem we have

$r=6/2=3\ in$ ----> the radius is half the diameter

$h=9\ in$

$\pi =3.14$

substitute the values

$V=\frac{1}{3}(3.14)(3)^{2}(9)$

$V=84.78\ in^3$

If l an m are parallel. Find the value of x and y

Svetllana [295]

(8y + 17) = (6x - 7)

(3x -29) + (6x -7) = 180
9x -36 = 180
9x = 216
x = 24

(8y + 17) = (6x - 7)
8y + 17 = 6(24) - 7
8y + 17 = 144 -7
8y = 120
y = 15

I hope this helps!! (and hope it’s correct hahah :))

Answer: Option 1

<u>Step-by-step explanation:</u>

$\begin {array}{l|c|c||l}&\underline{\quad Length\quad}&\underline{\quad Width\quad}&\underline{\qquad Area\qquad}\\ Current&3x&x&3x\cdot x=3x^2\\Option\ 1\ (triple)&3(3x)=9x&3(x)=3x&9x\cdot 3x=27x^2\\Option\ 2\ (3\ closets)&3x&x&3(3x\cdot x)=9x^2\\\end{array}$

Option 1 has a greater area than option 2.
