What you need to do is find the smallest multiple that they both have (i forgot what that is called) list them like this:
12: 24 36 48 60 72
15: 30 45 60 75
60 is the lowest number that they both can multiply to
60 cups/lids is the answer
The first one would be 120 the second one would be 68
Volume of a cylinder of radius r and heigth h is

Here h is 15 cm and r is 6 cm.
You need to find the hypotenuse of the right triangle.
4² + 9² = c²
16 + 81 = c²
97 = c²
9.85 = c
There are 5,280 ft in a mile.
Multiply 9.85 by 5,280.
9.85 × 5,280 = 52,008
Multiply 52,008 by 110.
52,008 × 110 = <span>5,720,880
The estimated cost for constructing the street would be $</span>5,720,880.
