please help!!! HARDEST MATHS QUESTION EVER it will make your brain hurtWatch
Occams Razor, the simplest solution is usually the right one.
We put down the pen and walk away because there isn't an answer.
1. how long the perimeter of the fence is.
2. what the perimeter of a semicircle is in terms of
3. how much leftover perimeter is used for the fence.
4. how long the "long side" of the rectangle is in terms of
With all of the above you should be almost done with the first part.
The base of the semicircle has a length of 2r.
The length of the curve in the semicircle is pi * r
If the fence is 250 long, then 250 = semicircle curve + 3 sides of the rectangle.
We can also say that the difference in length between the curved semicircle line and the straight rectangle edge is going to be pi * r - 2 * r which is (pi-2)*r.
is this getting you anywhere towards finding the area?
