grant starteda marathon at 8:00 A.M. he took 4 hours 49 minutes to complete the marathon. when did he crosd the finish line

Answers

If he starts at 8:00 AM and you start counting up by 1 hour at a time...

8:00 - 9:00 = 1 hour
9:00 - 10:00 = 1 hour
10:00 - 11:00 = 1 hour
11:00 - 12:00 = 1 hour

So far that is 4 hours that have passed and we are up to 12:00. Now remember, when we reach 12:00 we switch from AM to PM (that's 12 noon).

We only have 49 minutes left so now we just add that in

12:49 PM is when he crossed the finish line.

To solve, simply follow the way of finding the volume of a cylinder.

Calculate volume of a cylinder: V = πr2h.

Calculate the lateral surface area of a cylinder (just the curved outside)**: L = 2πrh.

Calculate the top and bottom surface area of a cylinder (2 circles): T = B = πr. ...

Total surface area of a closed cylinder is:
