Answer 13. = 12.9
Answer 14. = 15.1
Answer 15. = LM or PN (Any works pick one)
(13.) To find the circumference of a circle you have to use the formula
pi x d. The pi is 3.14 so you have 3.14 x 4.1 for the first question.
After multiplying, you should get 12.874 that is rounded off to 12.9.
(14.) To find the length of a arc, you have to use the formula 2pi(r)(0/360).
The r in this case is 4ft and the arc degrees measure 216. So you should get:
2(3.14)(4)(216/360) which equals 15.072 and rounded 15.1
(15.) A major arc is a arc of a circle that measures greater than or equal to (radians). When it saids "Name a major arc" This means there can be more than one and there is. The two major arcs are LM and PN. any will work.
