What is more important, π or e? Why?
Svetradugi [14.3K]
Well, this is a broad question but I would say pie. Pie is used very early on in secondary school and therefore a lot of people already know about it and how to use it. But for example if your a banker E would be more important as banks use e to calculate interest.

Hope this helps, have a great day.

A cylindrical rain barrel with a diameter of 2.5 feet and a height of 3.5 feet is filled to a height of 1.5 feet. How many more
scoray [572]
To answer this question you will need to find the total volume the rain barrel can hold. Then find the volume of water that it is currently holding.

Subtract these two amounts to find the total amount of water or can still hold.

Then convert this amount to gallons.

1. V = pi x r^2 x h
3.14 x 1.25^2 x 3.5
V = 17.17 cubic feet

2. Same formula
3.14 x 1.25^2 x 1.5
V = 7.36 cubic feet

3. 17.17 - 7.36 = 9.81 cubic feet

4. 9.81 x 7.5 = 73.575 gallons or approximately 74 gallons.
