24 = 250/100 * x ;
24 = 2.5 x ;
↔ 2.5 x = 24 ;
2.5 x / 2.5 = 24/ 2.5 ;
x = 9.6 ;

Answer:
40 problems in 100 minutes
Step-by-step explanation:
This is a ratio problem.
You first divide 30 minutes by three to get how many problems she can do in 10 minutes. What you do to one side you do to the other side. So then, you should have 4 problems in 10 minute. Then, you multiply 10 by 10 and 4 by 10 to get 40 problems in 100 minutes.
Volume of the cylinder can be calculated as:
V=πr²h
Radius = r = 4
Height = h = 7
π = 3.14
Using the values, we get:
V = 3.14 (16) (7) = 351.68 cubic units
So the answer to this question is 351.68
