Answer:

A = 532 ft^2 total

Step-by-step explanation:

There are 3 sets of 2 identical areas: 2 top/bottom, 2 sides, 2 ends.

Suppose the length is 14 ft, the width 7 ft and the height 8 ft.

A = 2 * (base area) + 2 * (end area) + 2 (side area)

= 2 * (98 ft^2) + 2 * (56 ft^2) + 2 (112 ft^2)

= 196 ft^2 + 112 ft^2 + 224 ft^2

A = 532 ft^2 total

Answer:

1/2

Step-by-step explanation:

remember that the formula for the slope of a line is

$m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

where m is the slope, and the x and y variables are the x-y coordinates of two points. Choose two points on the line:

Point 1 : (-1,3) and Point 2 : (1,4)

Plug in your values:

$m=\frac{4-3}{1-(-1)}$

$m=\frac{1}{2} \\$

So the slope of this line is 1/2 !

Find volume of cylinder <br><br> Show work

zloy xaker [14]

For this case we have that by definition, the volume of a cylinder is given by:

$V = \pi * r ^ 2 * h$

Where:

A: It is the radius of the cylinder

h: It's the height

We have according to the data that:

$r = \frac {34} {2} = 17 \ m\\h = 27 \ m$

Substituting in the equation we have:

$V = \pi * (17) ^ 2 * 27\\V = \pi * 289 * 27\\V = 24501.42\ m^3$

ANswer:

$V = 24501.42\ m^3$

A wooden toy kit has different painted solids. One solid is a cylinder with a diameter of 2cm and a height of 14cm.

jeka57 [31]

Answer:

Surface are = 94.24 cm2

Cylinders =4,244

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Surface area of a cylinder = 2π (diameter/2) h + 2π (diameter /2)²

Replacing with the values given

s = 2π (2/2) 14 + 2π (2/2)²

s = 87.96+ 6.28 =94.24 cm2

Since:

1 m2 = 10,000 cm2

40 m2 = 400,000 cm2 (area that one can of paint covers)

We have to divide the area that one can of paint covers by the surface area of each cylinder:

400,000/94.24 = 4244 cylinders
