A twelve inch pizza is cut into eight congruent pieces. What is the length of outer crust on each piece of pizza?

Solution:


A twelve inch pizza means:

r=d%2F2=12%2F2=6 


is cut into eight congruent pieces means: 

theta+=+%282%2Api%29%2F8=pi%2F4 

arclength+=+r%2Atheta=6%2A%28pi%2F4%29=4.71 

outer crust is 4.71inches
