Best ResponseYou've already chosen the best response.2hmmm the arc length is 100 degrees? as opposed to 100 meters?

Best ResponseYou've already chosen the best response.0I have no clue. i guess its safe to assume that cause all it says is the arc length is a 100 degrees. The length of that stretched out is 7 meters. So i have to find the perimeter of the sector which i dont even know what that is.

Best ResponseYou've already chosen the best response.0I thought that was the arc length

Best ResponseYou've already chosen the best response.0cause thats the central angle

Best ResponseYou've already chosen the best response.2right, but the arc's lenght is not given in degrees, it'd be a flat measuring unit, like meter, or feet now, the central angle of the arc, would be 100 degrees

Best ResponseYou've already chosen the best response.2so..hmm it sounds a lot like dw:1441238753083:dw if that's the case, all you'd need to get is the arc's length and sum it to the radii given

Best ResponseYou've already chosen the best response.2\(\bf \textit{arc's length}=s=\cfrac{\theta\cdot \pi\cdot r }{180}\impliedby \theta\textit{ in degrees}\)

Best ResponseYou've already chosen the best response.2so the perimeter is 7 + arc's length + 7

Best ResponseYou've already chosen the best response.0can i put 16pi/3 for exact???? as the arc length??

Best ResponseYou've already chosen the best response.2well.. you could also keep as rational as well got any choices on what's expected? float or rational?

Best ResponseYou've already chosen the best response.2well... I get another figure https://www.google.com/search?client=opera&q=7%2B(100*pi*7/180)%2B7&sourceid=opera&ie=utf8&oe=utf8&channel=suggest&gws_rd=ssl

Best ResponseYou've already chosen the best response.0what would be the exact form

jdoe0001

Best ResponseYou've already chosen the best response.2\(\bf \cfrac{\theta\pi r}{180}\implies \cfrac{100\cdot \pi \cdot 7}{180}\implies \cfrac{35\pi }{9} \\ \quad \\ 7+\cfrac{35\pi }{9}+7\implies 14+\cfrac{35\pi }{9}\)

Best ResponseYou've already chosen the best response.0That would be the perimeter?

Best ResponseYou've already chosen the best response.2we could use 3.1416 for \(\pi\) , then again, that'd make it a float, or decimal :)

Best ResponseYou've already chosen the best response.0yeah. Can u help me on one last question please??

Best ResponseYou've already chosen the best response.0Solve using S=r(theta) Radius Central Angle Arc length ? pi/3 3/2 m

Best ResponseYou've already chosen the best response.2very straighforward you said it >S =r(theta)

Best ResponseYou've already chosen the best response.2\(\frac{\pi }{3}\) is already in radian units so S = r * \(\theta\)

Best ResponseYou've already chosen the best response.0everytime i solve it i get a weird decimal and its confusing me
