Answer:
350.82
Step-by-step explanation:
To find the surface area, you must add up all of the areas of each shape of the prism in order to get the sum surface area.
The rectangle's area (
):

The triangle's area (
):


Now add up all the sides. (3 Rectangles, 2 Triangles.)


The total surface area is 350.82 cm squared.
This is a combination problem.

Answer:
-2x + 1
Step-by-step explanation:
3 + 7x - (2 + 9x)
Distribute the negative:
3 + 7x - 2 - 9x
Combine like terms:
-2x + 1
We can see that there are 5 CDs, each of radius 9 cm
<u>Area occupied by 1 disc:</u>
Area of a circle = πr²
Area of disc = π(9)²
Area of disc = 3.14 * 81 = 254 cm²
<u>Area occupied by 5 discs:</u>
Area occupied by 5 discs = Area occupied by 1 disc * 5
Area occupied by 5 discs = 254 * 5
Area occupied by 5 discs = 1270 cm²
