From Heath:
I am building a fence around a water tank. the fence is to be in the shape of a normal octagon. The tank has a circumference of 57 ' 6''. I would like the fence to be 3 ft from the tank at the skinny point . How would I calculate(for the simple guy) where to set each of my 4x4 posts at the 8 corners. Any help would be greatly appreciated.

22 people playing 6 rounds of golf |
2011-01-31 |
|
From angi:
I'm having a problem scheduling matches for a golf vacation.
We have 22 people playing 6 rounds of golf.
We know that we will need to have two 3 man pairings each day.
Is there a way to make sure that is not a great deal of duplication.
I did see how Penny answered a question in 2005 with the circles.
Is there a way mathematically to do this or through excel?

From Marie:
A baseball diamond is a square with side 90 feet in length. A player runs from second base to third base at a rate of 18 ft/sec. At what rate is the area of the trapezoidal region, formed by line segments A, B, C, and D changing when D is 22.5
Distance A is the players distance from first base when running from 2nd to third. Distance D is his distance from 3rd base. Distance C is the distance from 3rd to 3rd to Home. Distance B is the distance from Home to First.
I have found dA/dt in a previous problem.
