Set up an equation to represent the areas of the shapes in the table:
(area of rectangle) - 2(area of circle)
There is a 2 in front of the area of the circle, since there are two identical circles punched out of the rectangle.
First, find the area of the rectangle. The area of the rectangle is given by the following formula:
length * width
You already have your two values for length and width. Plug those values into the formula:
236 is the area of the rectangle.
Now we'll find the area of the circle.
The diameter of the circle is 2. The radius is one half of the diameter, so the radius is 1.
The area of a circle is found with the following formula:
pi is equal to 3.14, so replace the pi symbol with the 3.14. Then, plug your radius into the equation.
The area of the circles is 3.14.
Plug your areas into the first equation above.
The approximate area of the cardboard is
229.72.
1st way:
When Luis travels 216 mi, he will use :
1) minivan - 216 mi*18 gal/1 mi = 216*18 gal
2) compact - 216 mi/24 mi/gal = 216*24 gal
He will save 216*24 - 216*18 = 216(24 -18)= 1296 gal
2d way.
For 1 mi he saves 24 -18 = 6 gallons
For 216 mi he saves 216*6 = 1296 gal
Answer:
13.5
Step-by-step explanation:
area of base < 27 m^2
width = height - 9
length = 6
area of base = width * length
(height - 9)*6 < 27
height < 27/6 + 9
height < 13 .5 (maximum height)
Here you go:
3 to five or 5 to 3
