Answer:
8.7
Step-by-step explanation:
Add up all the books
5 students have 6 books each
3 students have 8 books each and so on
5 * 6 = 30
8*3 =24
9*6 = 54
12*4 = 48
-------------
156 books
Divide by the number of students
156/18 =8.6666666
Round to the nearest tenth
8.7
The average ( or mean) number of books per student is 8.7 books
Start with the formula of the volume of a cone
volume of cone = (1/3) pi * r^2 * h
Now you double the radius and the height.
The radius becomes 2r, and the height becomes 2h.
volume of cone = (1/3) pi * (2r)^2 * 2h
= (1/3) pi * 4r^2 * 2h
= (1/3) pi * 8r^2 * h
= 8 * (1/3) pi r^2 * h
As you can see, the volume became 8 times larger.
8 * 350 cm^3 = 2800 cm^3
