IS the answer 37.68?
OpenStudy (anonymous):
wait i think it is..
OpenStudy (anonymous):
No it isn't. Thats the circumference (or perim) of the entire circle. This is a semi circle.
OpenStudy (anonymous):
C = Pi * Diameter C = 3.14 * 12 C = 37.68 This is the circumference of the full circle. We need to divide it by 2 C = 37.68/2 C = 18.84 Now we need to add the diameter C = 18.84 + 12 C = 30.84 This is the perimeter of a semi circle! Here's a link to help you visualize it if you dont understand it http://www.mathvillage.info/node/159
