Answer:
64 square ft^3
Step-by-step explanation:
If the side lengh is 3 then you would have 4^3 which is 64.
The correct answer is C. So, lets go first to the equations that determine the volume of these solids. For the cylinder, that is simple; pi*r*r*h where r is the radius, h is the height and pi is the constant 3.14. For the cone, it is not easy to derive but one gets that the formula is:

.
We notice thus that

. That holds irrespective of their radius or height; we only need to know that the heights and radii of the two objects are the same. Now, we have thus that:

.
We can check if this holds for Jared's statement; 1178/4712=0.25=1/4. So, it does not hold and thus Jared's statement is incorrect.
Answer:
A) 10.00
Step-by-step explanation:
10.00 x 0.8 is equal to 8 giving a total of 18.00. But it is incorrectly done in the table.
Answer:
The answer is 600 minutes (10 hours)
Step-by-step explanation:
20 minutes = 1 student.
30 students x 20 = 600 minutes
600mins / 60 (because an hour has 60 mins) = 10 hours.
