What is the elapsed time from 6: 45 am to 3: 28 pm

6:45a to 7:45  = 1 hour

7:45 to 8:45  = 2 hours

8:45 to 9:45  = 3 hours

9:45 to 10:45 =  4 hours

10:45 to 11:45  = 5 hours

11:45 to 12:45  = 6 hours

12:45 to 1:45  =  7 hours

1:45 to 2:45  = 8 hours

2:45 to 3:00  = 8 hours and 15 minutes

then just add the 28 minutes to the 15 minutes

28 + 15 = 43

6:45a to 3:28p = 8 hours and 43 minutes.

Hope this helps.

The equation for the volume of a cylinder is:
V = height * area of base
A cylinder has a circle for a base, and the equation for the area of a circle is:
A = pi * r^2

We know the area of the base, so plug it into the volume equation:


Now input the height and radius of the cylinder:



Thus, the volume of the cylinder is 12pi, or 37.699111...
