Answer:
Step-by-step explanation:
Let x be the number of buses and y be the number of vans.
We know that there are 5 more buses than vans, therefore, we can set up:

Since a bus transports 55 people and a van transports 12 people, therefore, we can set up:

Now lets solve the above two equations together by substitution

Total number of students and teachers who rode to the zoo in buses
Total number of students and teachers who rode to the zoo in vans

➷ The formula for circumference is 
1) 
Divide both sides by 
d = 9.99 (consider this to be 10)
Half this to find the radius
10/2 = 5
It would be figure B.
2) 
Divide both sides by
:
d = 11.99 (consider this to be 12)
Divide by 2 to find the radius:
12/2 = 6
It would be figure C.
3) area = 

r^2 = 48.97515909
r = 6.998 (consider this to be 7)
It would be figure D
4) 
r^2 = 35.98174
r = 5.998 (consider this to be 6)
It would be figure C.
5) radius = diameter / 2
radius = 3

It would be option C
