The ratio of the length to width of a rectangle is 3:4 the perimeter is 56 in, find the length and the width
Verizon [17]

Answer: Length is 12in and width is 16in

Let's use the ratio method!

3+3+4+4 is 14

Let's think the length as," L " and the width as," W "

L / 56 = 3/14

L = 3/14 * 56

L = 12

And for width:

W / 56 = 4/14

W =4/14 * 56

W = 16

There you go! We did it!

A cylinder has a radius of 5 feet and a height of 8 feet. Which of the following can be used to calculate the volume of a cone t
Lilit [14]
The answer is 1 over 3(3.14)(5²)(8) 

The volume of the cylinder (V1) is:
V1 = π · r² · h                (r - radius, h - height)

The volume of the cone (V2) is:
V2 = 1/3 π · r² · h         (r - radius, h - height)

It is given:
r = 5 feet
h = 8 feet
π = 3.14

Therefore, the volume of the cone is:
V2 = 1/3 · 3.14 · 5² · 8   which is the same as 1 over 3(3.14)(5²)(8).
