honestly I have no idea what the answer is but I need so more points so I decided to do the question
Answer:
there must be at least 6 chaperones
Step-by-step explanation:
25 x 3= 75 so 2 chaperons x 3= 6 with a remainder of 5 students

Volume of a cone = 1/3 π r² h
a+b/2*h
Here,
a = 12xcm
b= 15xcm
h= 7cm
(12+15)xcm/2*7
=27xcm*3.5
