Answer: 13750+262=14,012 ft^3

Step-by-step explanation:

Hello!!!

Find the volume of the bottom and top separately and then add them. Cylinder volume is the area of the bottom times the height (22/7)(5^2)•175=13750 ft^3

The volume of a sphere isV=(4/3)(22/7)r^3where r is the radius. also 5 since it fits on the cylinder. Also we only want half the sphere so useV=(2/3)(22/7)•5^3=261.9 ft^3 round upto 262. Now add together 13750+262=14,012 ft^3

Hope this helps~!!!!!

36 students have traveled outside of the United States, when there are total 120 sixth graders.

Explanation

The number of students traveled outside of the United States is 9 when there is total 30 sixth graders. So, the ratio of the student traveled to the total students will be $9: 30 = 3: 10$

Now there are total of 120 sixth graders in the school and lets assume the number of students traveled outside the United states is $x$ . That means the ratio...

$x: 120 = 3:10 \\ \\ \frac{x}{120}=\frac{3}{10} \\ \\ 10x=360\\ \\ x=\frac{360}{10} \\ \\ x= 36$

So, 36 students have traveled outside of the United States.
