Which has a greater volume; two regular cans of soup, each with a diameter of 8 cm and a height of 10 cm or one family size can

Sophie [7]

Answer:

The two regular cans of soup has a greater volume than the family size can of soup

Step-by-step explanation:

step 1

Find the volume of two regular cans of soup, each with a diameter of 8 cm and a height of 10 cm

The volume is equal to

$V=2[\pi r^{2} h]$

we have

$r=8/2=4\ cm$ ----> the radius is half the diameter

$h=10\ cm$

substitute

$V=2[\pi (4)^{2} (10)]$

$V=320\pi\ cm^{3}$

step 2

Find the volume of one family can of soup, with a diameter of 10 cm and a height of 12 cm

The volume is equal to

$V=\pi r^{2} h$

we have

$r=10/2=5\ cm$ ----> the radius is half the diameter

$h=12\ cm$

substitute

$V=\pi (5)^{2} (12)$

$V=300\pi\ cm^{3}$

therefore

Compare the volumes

$320\pi\ cm^{3} > 300\pi\ cm^{3}$

The two regular cans of soup has a greater volume than the family size can of soup

Write an equation of the line that passes through the given point and is perpendicular to the given line.

topjm [15]

Answer:

y = - 3x - 22

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = $\frac{1}{3}$ x + 1 ← is in slope- intercept form

with slope m = $\frac{1}{3}$

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{\frac{1}{3} }$ = - 3 , then

y = - 3x + c ← is the partial equation

To find c substitute (- 6, - 4) into the partial equation

- 4 = 18 + c ⇒ c = - 4 - 18 = - 22

y = - 3x - 22 ← equation of perpendicular line
