Answer:

Step-by-step explanation:

You first need to find the surface area of a completely open cylinder. That formula is

SA=2\pi rh Using 3.14 for π, we find the area of the material that is needed to make this pipe:

SA = 2(3.14)(1)(30)

SA = 188.49 square feet.

If it costs $3.50 per square foot and you have 188.9 square feet, we multiply the cost per square foot times the number of square feet:

188.49(3.50) = $659.40, choice B.

Answer:

125

Step-by-step explanation:

Find the surface area of the table that Raj wants to cover.

Since the side table is a cube each side is identical.

Step 2:

Raj wants to cover 5 sides of the cube. Therefore the total surface area to be covered is 5 · 30 · 30 = 4,500 square inches.

Step 3:

Find the surface area of each tile.

The surface area of each tile is 6 · 6 = 36 square inches.

Step 4:

Find the number of tiles needed to cover the table.

4,500 square inches

36 square inches per tile

 = 125 tiles

Raj will need 125 tiles to cover the table.

<span>the triangle DEF is translated following the rule
</span>(x,y)-----> (x+2,y+2)
in the translation the figure maintains its dimensions
so
the area of triangle DEF is equal to the area of the triangle D’E’F’

therefore

the answer is
<span>The area of triangle D’E’F’ is equal to the area of triangle DEF. </span>
