Answer:
628.32
Step-by-step explanation:
Volume of a cone = 1/3 π r² h
We see that the area is 159 3/8 and the length is 18 3/4.
Because the area is the length*width, to find the width, we must divide the area by the length.
Think of it this way:

Divide l on both sides:

And w is what we're looking for.
So, divide 159 3/8 by 18 3/4.
You should get that the width is 8.5 feet :)
Answer:
the longest side is 25
Step-by-step explanation:
the equation would be x+ x+1 + 7 for the 3 sides of the triangle
x + (x+1) + 7=56
combine like terms
2x+8 = 56
subtract 8 from each side
2x = 48
divide by 2
x = 24
the sides are
x=24
x+1 = 25
7
the longest side is 25
