Answer:
Step-by-step explanation:
a + c = 92.....c = 92 - a
8a + 5c = 688
8a + 5(92 - a) = 688
8a + 460 - 5a = 688
3a = 688 - 460
3a = 228
a= 228/3
a = 76 <==== adults
a + c = 92
76 + c = 92
c = 92 - 76
c = 16 <=== children
Trapezoid has only 1 pair of parallel
The equation for circumference is
![c = 2r\pi](https://tex.z-dn.net/?f=c%20%3D%202r%5Cpi)
Since you have the diameter you can either divide the diameter (d) by two to get the radius (r), or you can divide two from the equation to give you
![c = d \pi](https://tex.z-dn.net/?f=c%20%3D%20d%20%5Cpi)
So the circumference is 33*pi meters, approximately 103.62 meters
