perimeter...im really bad at math :b
I am too. I'm not sure how to answer this sorry
Every perfectionist was once a beginner.. :)
its ok :)
Well good luck! :)
That track is made up of Rectangle and two semicircles..
|dw:1437508710133:dw|
If the semicircle is having same radius then two semicircle = 1 cirle..
ok
But you need to find the perimeter of inside track, so go with mathstudent55..
ok then thx
The track is made up of 2 line segments each 130 m long. Then the track also is made up of 2 semicircles. Two semicircles combine to form one circle. P = 130 m + 130 m + circumference of circle. To find the circumference of the circle use the formula, \(C = \pi d\) You are given d, the diameter as 56 m.
you can notice that inner track diameter is 56m...
\(P = 130 m + 130 m + \pi \times 56 m\)
so now do i do pie times diameter?
ok thank you so much! @mathstudent55 and u too :) @waterineyes
would my answer be 435.84?
Yes. pi * diameter is the full circle's circumference. Then you add that to 130 + 130.
Correct.
ok thank you!
You're welcome.
