## anonymous one year ago The figure shown is a salinon. It is bounded by four semi circles. Determine the perimeter of the salinon to the nearest tenth of an inch.

$\pi d/2 + d$

3. anonymous

where d is the diameter

4. anonymous

That is the perimeter of a semicircle

5. anonymous

First find the perimeter of the large semi circle

6. anonymous

the one with diameter 6

7. anonymous

15.42? @10115658

8. anonymous

give me a sec

9. anonymous

now find the perimeter of the smaller semicircles

10. anonymous

sorry 3pi + 6

11. anonymous

the perimeter of the smaller semicircles is pi + 2

12. anonymous

so 4pi + pi + 6 - 2pi - 4

13. anonymous

5.14? @10115658

14. anonymous

or pi +2

15. anonymous

21.1327412? @10115658

16. anonymous

3pi + 2 is the answer

17. anonymous

actually its 2pi+2

Thank you for all your help!! @10115658
