The sixth grade makes 3.09 per hour
The seventh graders make 2.54 per hour
the eighth graders make 2.90 per hour
So the sixth graders make the most per hour. you can check this answer by taking the amount of money made and divide it by the time that it takes to raise the total amount of money raised by each class of students.
Volume of a cone can be found using the equation 1/3 π r² h (or π r² h / 3)
17.6 is the diameter so divide that by 2 to get the radius which is 8.8
(1/3)π(8.8²)(23.4) = (1/3)π(77.44)(23.4) = (1/3)π(1812.096) = (604.032)π
if you need a more specific answer and pi can equal 3.14 then it equals 1896.66048
