A cone shaped popcorn cup has a radius of 5 cm and a height of 9cm. How many cubic cm of popcorn can the cup hold? Use 3.14 as a
katovenus [111]

Answer:

The cup can hold <u>235.5 cubic cm</u> of popcorn.

Step-by-step explanation:

Given:

A cone shaped popcorn cup has a radius of 5 cm and a height of 9cm.

Use 3.14 as an approximation for pi.

Now, to find cubic cm of popcorn the cup can hold.

Radius ( r ) = 5 cm.

Height ( h ) = 9 cm.

π = 3.14 ( as per question ).

So, to get the cubic cm of popcorn the cup can hold we put formula of volume:

Volume = \pi r^2\frac{h}{3}

Volume=3.14\times 5^2\times \frac{9}{3}

Volume=3.14\times 25\times 3

Volume=235.5\ cubic\ cm.

Therefore, the cup can hold 235.5 cubic cm of popcorn.

Write the equation below in slope-intercept form. <br><br> x - y = 2
Arte-miy333 [17]

slope intercept form

y=mx+b

x-y =2

we need to subtract x from each side

x-y-x = -x +2

-y = -x+2

multiply each side by -1

-1*-y = -1(-x+2)

y = x -2

the slope intercept form is

y = x-2

Write an equation for the line that is parallel to y=-4x+2 and goes through (0,7)
Soloha48 [4]

Answer:

The answer is

<h2>y = - 4x + 7</h2>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

The original line is y = - 4x + 2

Comparing with the general equation above

Slope / m = - 4

Since the lines are parallel their slope are also the same

Slope of parallel line = - 4

So the equation of the line using point (0,7) and slope - 4 is

y - 7 =  - 4(x - 0) \\ y - 7 =  - 4x

We have the final answer as

<h3>y = - 4x + 7</h3>

Hope this helps you
