Give your answer as completely simplified exact value in terms of pi, no approximations.
00:07
So first of all, to find the perimeter, i have to find the length of this side.
00:14
So i would do 6 squared plus 6 squared equals c squared.
00:20
So i'd have 36 plus 36 equals 72.
00:29
And then i would have to find the square root of 72 so this is the square root of 72 because it does not want me to use approximations let me see if i can actually get that a little bit more specific 72 divided by two to 36 6 6 2 2 3 3 3 so square root of 72 is three twos, two threes.
01:11
So that would equal six the square root of two.
01:16
So let me just write this, simplified completely, six times the square root of two.
01:24
And now i'm going to find the circumference of half of that circle.
01:30
So the circumference equals pi times diameter.
01:34
So i'm going to do pi in the calculator.
01:41
Times the diameter of six.
01:47
So six times pi is the circumference is 18...
