The perimeter of the school crossing sign is 102 inches. What is the length of each side?

1 answer:

4 0

The perimeter of a shape is the total length of the border of the shape

s + 6 + s + 6 + s + s + 2s = 102
6s + 6 = 102
6s = 102 - 6
6s = 96
s = 96 ÷ 6
s = 16

The length of each side is

s + 6 = 16 + 6 = 22
s + 6 = 16 + 6 = 22
s = 16
s = 16
2s = 2 × 16 = 32

10 POINTS! PLEASE HELP!! The illustration shows a compact disc tray that holds five CDs. The radius of each compact disc is 9 cm

MariettaO [177]

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
