tkhunny · Answer

Done.  Add that to 18.

Did you come up with 27.42?

tkhunny · Answer

$9\pi = 28.26$ since we are to use 3.14

anonymous · Answer

18 (which is the perimeter of the three side) + (3.14x6)(for the perimeter of the whole circle) divided by 2 to give me half the circle =27.42 ?

or did i forget something???

tkhunny · Answer

Whoops.  I forgot the figure.  The diameter is 6.

6 + 6 + 6 + 3pi = 18 + 3pi = 27.42

You got it!  I managed to forget what we were doing!  Sorry about that.
