Answer:
259 Students
Step-by-step explanation:
So, since there are 37 children in each bus, and 7 busses, we need to multiply the two together.

V=hpir^2
d/2=r
5/2/2.5
h=7
V=7pi2.5^2
v=7pi6.25
V=43.75pi
aprox pi=3.141592
V=137.44465
V=43.75pi ft^3 or aprox 137.44465 ft^3
(12+13=25) (25+26=51) 51 is You're answer.
Hope this helps! :)
