Can he go inside the shed? And is he/she connected by a chain that is connected to the corner of the shed?

No he's not connected. I'm not sure. That's all my teacher wrote

he has to be connected by a chain to the shed right?

Unkle Rhaukus I like your drawings, but what is the actual value?

FellowrootBest ResponseYou've already chosen the best response.2
I'm very sure I know how to do it. Just give me some time to work it out.

im not sure why you had to integrate

we know the are of a circle is πr^2, so a semicircle has area (πr^2)/2 and a quater circle has area (πr^2)/4

FellowrootBest ResponseYou've already chosen the best response.2
I integrated because I wanted to take the whole circle and then subtract the parts where the goat can't go. The area of the top of the circle is curved and the goat can't go there. So I created a function and integrated it so that I could find that exact area that is fenced off.

@ AdhaZeera Do you understand what I did when I integrated. I will explain it to you if you want. I used calculus to arrive at that answer.

the sector is 1/12 of a circle

FellowrootBest ResponseYou've already chosen the best response.2
@ UnkleRhaukus I know that there is a formula that is A= (theta)r^2/2 but I don't how it works here.
 one year ago

UnkleRhaukusBest ResponseYou've already chosen the best response.0
\[A=\frac{\pi\times 3^2}4+\frac{\pi \times8^2}{2}+\frac{\pi \times8^2}{12}+\frac{4\times 8}{2}\]\[=\pi\times\frac{465}{12}+16\]\[\approx 140\]

well theta was 30° right? angles of segment / angle in circle \[30°/360°=1/12\] area of segment / area of circle \[\frac{\pi r^2}{12}\qquad/\qquad\pi r^2\]

i had to use a trig ratio to to get 30° btw

Your value comes to 140.35 mine is 141.7, its off only by a hair and is a very good approximation, but mine is exact.

where did i error?

not sure, but its pretty darn good.

\[A=\frac{\pi\times 3^2}4+\frac{\pi \times8^2}{2}+\frac{\pi \times8^2}{12}+\frac{4\times 8}{2}=\pi\times\frac{475}{12}+16\approx140.35\]

@Fellowroot i think we got different answers because we were solving different regions our pictures are different

dw:1350891993500:dw The only thing I don't know if that if the 5 feet fence touches the edge of the circle or if there is a gab. For the solution i provided it doesn't matter though. On my pic, the 'x', I really don't know that distance, it may make a difference for your answer, i don't know.
