V = 4/3 (pi) r^3
ball with radius of 18 cm...
V = 4/3(3.14)(18^3)
V = 4/3(3.14)(5832)
V = 24429.02
ball with radius of 12...
V = 4/3(3.14)(12^3)
V = 4/3(3.14)(1728)
V = 7238.23
24429.02 - 7238.23 = 17190.79 greater <====

14) Note that Carlos travels 12 miles from school to home (and vice versa). Note also that it is only asking for "to school", and for 5 days.
Multiply 5 with 12
12 x 5 = 60
60 miles is your answer.

15) Note:
Mandy travels 9 trips, and each trip is 10 miles
Matt travels 11 trips, and each trip is 8 miles.
Multiply each number to corresponding.
Mandy = 9 x 10
Mandy = 90
Matt = 11 x 8
Matt = 88
Mandy travels more miles than Matt by 2 miles

Answer:
So for our trapezium, the top side length is a, the bottom side length is b and the height is h.
So assuming b > a, b - a will give the length of the base of the two triangles. So you now have a rectangle, a by h (and the area ah) and two triangle, each with a base of (b-a)/2 triangle and height h. The area of the two triangles is just (b-a)/2 * h or h(b-a)/2.
The total area is h(b-a)/2 + ah = h(b-a)/2 + 2ah/2 = h(b-a+2a)/2 = h(b+a)/2
