First, we know L and W are the same number. The in the end the Length is 6 more, therefore we add 6. The equations begins as so
2x+6=27
-6
2x=21
/2
x=10.5
+6
Therefore the Width =10.5 M
The Length = 16.5 M
Answer:
undefined
Step-by-step explanation:
0/0 = error
Find the volumes of the two cones and subtract.
V = 1/3 * pi * r^2 * h
V = 1/3 * 3.14 * 6^2 * 9
Simplify exponent:
V = 1/3 * 3.14 * 36 * 9
Multiply:
V = 339.12
V = 1/3 * pi * r^2 * h
V = 1/3 * 3.14 * 3^2 * 6
Simplify exponent:
V = 1/3 * 3.14 * 9 * 6
Multiply:
V = 56.52
Subtract the two volumes:
339.12 - 56.52 = 282.6
So the Garden Landscaping Company purchased 282.6 ft^3 of gravel.
A variable is a symbol that’s used in a number. It typically uses a variation of letters such as x,y,etc. for instance 3x=6
