Answer:

Step-by-step explanation:

The formula is area of circle x height

To find area do radius x radius x 3.14 so 49 x 3.14 = 153.86

Since the answer already has pi just do 49 x 10 = 490

Given:

Radius,r =7cm
height ,h=10cm

To find out:

the volume of the cylinder

Formula used:

$\pi \: r {}^{2} h$

Solutions:

$volume \: of \: cyli. = \pi \times 7 \times 7 \times 10$

$volume \: of \: cylinder= \red {490\pi}$ cm²

Answer:

So all the possible solutions are:

$\bold{523,~400,~379~and,~378.6}$

Solution Steps:

First you need to solve the real inequality to understand how to find the rest of the possible equations.

Add 78 to both sides:

$78+78=$ Cancels Out

$300+78=378$

So now we know the real answer, but it ask for all possible answers.

(Means anything larger than 300 when you plug it into x - 78 > 300.)

Numbers that are greater than 378:

1.) $377-78=299 > 300$ (False)

2.) $523-78=445>300$ (True)

3.) $0-78=-78>300$ (False)

4.) $-62-78=-140>300$ (False)

5.) $400-78=322>300$ (True)

6.) $379-78=301>300$ (True)

7.) $222-78=144>300$ (False)

8.) $378.6-78=300.6>300$ (True)

Which equation represents the graphed function?

umka2103 [35]

you know that (0,3) is a point and (1,1) is another point.

so now you have to replace them in the follow equations.

i did that and the right answer is the first equation => y=-2x+3
