Step-by-step explanation:
Given:
Let 'x' be the number of questions worth 5 points.
Let 'y' be the number of questions worth 2 points
Total Number of Problems = 29

Answer:
<em>628 </em>
Step-by-step explanation:
Since the formula to find the volume of a cylinder is h, we just need to fill things in.
Since the radius is 5 and the height is 8 and we know that pi=3.14, our new equation is:
3.14*5^2*8.
5*5=25. Now we simplify.
3.14 * 25 * 8
78.5 * 8
<em>628 </em>
Hope this helps!! <3 :)
