Answer:

153 square units

Step-by-step explanation:

The figure is drawn in the attachment with some lengths and points labeled.

The figure can be considered to have an area that is the sum of the areas of rectangle ABFE and triangle FGH, with the area of triangle BCD subtracted.

That area is ...

A = area(ABFE) +area(FGH) -area(BCD)

= (15)(9) +(1/2)(9)(6) -(1/2)(6)(3)

= 135 +27 -9 = 153 . . . square units

What is the volume of a cylinder with r=3 and h=10

____ [38]

This is one of those questions where, if you know the formula, it's easy,
and of you don't know the formula, there's no way.

In fact, the whole purpose of the question is to help you remember the formula.

The volume of a cylinder is

   (pi) x (the radius)² x (the height).

For this particular cylinder, that's

    (pi) x (3)² x (10) =

   (pi) x (9) x (10) = 90 pi cubic units.

If you use (3.14) for (pi), then that's <em>282.6 cubic units</em>.

1/5(2x - 10) + 4x = -3(1/5x + 4)
0.4x - 2 + 4x = -0.6x - 12
4.4x - 2 = -0.6x - 12
5x - 2 = -12
5x = -10
x = -2
