first you need to find the slope (m) using y2-y1/x2-x1.

-4-2/4-1= -6/3=-2

m=-2

then plug into the intercept form formula: y-y1=m(x-x1)

y-2=-2(x-1)

A drum has a diameter of 26 inches and is 15 inches deep. Find the volume of this drum.

Rainbow [258]

Answer: 7964.97 in³

Step-by-step explanation:

A drum is a cylinder. Therefore, we will have to calculate the volume of a cylinder which will be:

Volume = πr²h

where π = 3.142

r = Diameter/ 2 = 26/2 = 13

h = 15

Volume = πr²h

= 3.142 × 13² × 15

= 3.142 × 169 × 15

= 7964.97 in³

If the walls are 9' high, how much paint would I need to buy to paint the walls of all three bedrooms?

ludmilkaskok [199]

Answer:

The required paint for a total of $1.404\ ft^{2}$ is approximate 6 gallons

Step-by-step explanation:

we know that

To find how much paint would I need to buy to paint the walls of all three bedrooms, calculate the area of all three bedrooms

Master Bedroom

The area is equal to

$A1=(16+16+12+2+18)*9=576\ ft^{2}$

2 Bedroom

The area is equal to

$A2=(12+14+10+10)*9=414\ ft^{2}$

3 Bedroom

The area is equal to

$A3=(10+10+14+10+2)*9=414\ ft^{2}$

The total area is equal to

A=A1+A2+A3

$A=576+414+414=1.404\ ft^{2}$

Approximate one gallon of paint covers 250 square feet

$1.404/250=5.6\ gal$
