OHHHH i see , i think the question is wrong. Its suppose to be different. We are solving without using PI, we add it at the end. i forgot how you saqy that in a question.

OpenStudy (anonymous):

so we just do 100*8?

jagr2713 (jagr2713):

Yes and what do we get?

OpenStudy (anonymous):

800

jagr2713 (jagr2713):
