Thanks in advance for the help.
I have included this image for clarity sake.
Ok first I get the Circ of the lower ARC (half circle)
Pie*12cm / 2 = 18.84955592
Then the two sides
6cm + 6cm = 12
Then the two quarters placed together make up a half circle so
Pie*8 / 2 = 12.56637061
then the top line joining the two quarters = 4cm
18.84955592 + 12 + 12.56637061 + 4
or 47.42 cm
Now according to my text book that is the wrong answer, now my book might just be wrong but I dont feel like I am the right one to debate that :)
Would anyone like to help??
