Answer:
129.996 cubic feet
Step-by-step explanation:
Assuming that the barrel is a perfect cylinder, we can use the formula to find the volume:
First, we have to find the radius, which is:
D = 2r
So the radius is 3 feet, since it is half of the diameter. Then, we plug in the values.
Now, we solve. Exponents are first...
3.14(9)(4.6)
Now multiply left to right.
28.26(4.6)
129.996 cubic feet
Therefore, the barrel can hold 129.996 cubic feet of oil. Hope this helps you!
Answer: 1,250
Step-by-step explanation:
Given: The total number of students in the school= 25,000
Since each class has 10 students , therefore, the number of classes in the school=
Also, Each student takes 2 classes a day, thus the number of classes taken by total teachers in a day =
Also, each teacher teaches 4 classes.
Then the number of teachers in the school =
Hence, the number of teachers are at Big Big School = 1,250
