How did you do?
Finished with this lesson! Thank you very much Bobbym for your help. Much appreciated!!
So I'm guessing I went wrong some where, but where?
That is very close to the exact answer of 7213.3.
Ok here is the "redo" for #7 - #10:
What do you want to do about 10, as you can see the expression is very complicated. Bob suggests you might submit an approximation.
Ok, so redoing #7 - #9:
Cool! So it would be:
3/4 x 10^2 x PI
No, remember you can not use the barn, so it is 3 / 4 of the circle.
Yes I understand that. The E-circle represents the entire range, the F-circle and G-circle represent the both ways the goat can go, and the H-circle (green) represents where they overlap. So would this just be considered as one area, as in just 10? Making the equation:
The green circle is the overlap of the two circles because going right or left you have the same center.
