Answer:

The answer to your question is: A = 1627.35 in²

Step-by-step explanation:

Data

height = 30 in

radius = 7 in

A = ?

Lateral area

  A = 2πrh

  A = 2(3.1416)(7)(30) = 1319.47 in²

Area of the base and lid

 A = 2 x πr²   = 2(3.1416)(7)²

                      = 307.88 in²

At = 1319.47 in² + 307.88 in²  = 1627.35 in²

Step-by-step explanation:

I'll leave the drawing part to you. However, you just have to note that if each of the tile is 1/2 ft, the height should be 5 squares and the width is 9 squares. The area of the section of the wall is calculated by multiplying the height and the width. 

                         A = H x W = (2 1/2 ft) x (4 1/2 ft) = 11.25 ft²

storchak [24]

Answer:

x= -2

Step-by-step explanation:

The first thing I did was isolate the x's on one side.  I subtracted 38x from both sides.  This gives me:

-9x=18.  

Now i divide both sides by -9.  Giving me x=-2
