Number of yards times 3. Say you have 6 yards you want to convert it into feet. So since there is 3 feet per yard you would do 6x3=18 feet so 6 yards is 18 feet

sleet_krkn [62]

Answer:

19,200 yds²

Step-by-step explanation:

The question is asking for how many <em>square yards</em> of grass is needed

This means that it is looking for the Area.

The formula for area is <em>Length x Width = Area</em>

<em>120</em> (Length)

<em>160</em> (Width)

<em>120 x 160</em> = 19,200

The unit of measurement is yards...

19,200 yds²

Subtract fraction and simplify if needed
Harrizon [31]
First you need to find the common denominator. both 6 and 7 go in to 42 evenly

multiply 5/6 by 7 to get 35/42
multiply 2/7 by 6 to get 12/42
subtract 12 from 35 to get 23

23/42

What is the surface area of the cylinder with height 7 cm and radius 5 cm? Round
nalin [4]

Answer:

376.991 cm²

Step-by-step explanation:

SA_{cylinder} = 2\pi r^{2}  + 2\pi rh

Surface Area = 2π(5²) + 2π(5)(7)

                      = 50π + 70π

                      = 120π

                      = 376.9911184... ≈ 376.991

<h2>Derive Surface Area of A Cylinder</h2>

If you take a look at a net of a cylinder, you can see it is composed of two circles(bases) and a rectangular strip with the length of the diameter of the circle

The formula for the area of a circle = πr², and since there are 2, it is 2πr²

The formula for circumference of a circle = 2πr, and since we are multiplying that by the height by the height of the cylinder, it is 2πrh

∴ 2πr² + 2πrh
