Answer:

A=777.54

Step-by-step explanation:

What you do is use the formula which is

a=2pirh+2pir^2.

The radius is half the diameter and the diameter is 15 so you take 15 and divide it by 2 to get 7.5.

The height is 9 m.

A=2(3.14)(7.5)(9)+2(3.14)(7.5)^2=777.54 m.

Answer:

 777.15 m^2

Step-by-step explanation:

To find the surface area of a cylinder

SA = 2 pi r h + 2 pi r^2

The area of the sides Plus the area of the top and bottom

We know the diameter is 15 so the radius  is 1/2 (15) = 7.5

SA = 2 * pi * (7.5) * 9 + 2  * pi * (7.5)^2

     = 135pi + 112.5pi

        247.5 pi

Approximating pi with 3.14

      247.5 (3.14)

     777.15 m^2

The values that completes the table are 28, 9, 33, 32 and -3

<h3>Tables and values.</h3>

Tables are used to represents the dependent and independent variable of a function. They are used to formulate function.

From the given table, we are to think of any dependent value and subtract 3 from it to get the equivalent independent value.

From the third column;

a3-3 = 25

a3 = 25 + 3

a3 = 28

For the fourth column

a4 = 12 - 3

a4 = 9

For the fifth column

a5-3 = 30

a5 = 30 + 3

a5 = 33

For the sixth column

a6-3 = 29

a6 = 29 + 3

a6 = 32

For the seventh column

0-3 = a7a

a7 =  0 - 3

a7 = -3

Hence the values that completes the table are 28, 9, 33, 32 and -3
