So we're told that a useful way to remember the number of seconds in a year is it's equal to pi times 10 to the seven seconds per year.
00:07
So in theory, the number of seconds per year or t is equal to pi times 10 of the seven seconds per year.
00:13
And we're asked to find the percent error when compared to the actual number.
00:16
So in reality, there are 365 .24 days per year.
00:31
And we can convert that into seconds per year.
00:35
And then we can compare that to the theory.
00:37
So we're going to call this the actual value.
00:40
So this is going to be multiplied by the hours in a day.
00:46
So there are 24 hours per day.
00:53
And then we can multiply this by the number of seconds in a day.
01:00
And there are 3 ,600, or excuse me, the number of seconds per hour...
