Answer: V=πr^2h=π·4^2·8≈402.12386cm^2
There is an app that will help for these types of questions called, "Showmath."
I think the answer is 5 because 25 divided by 5=5
35a + 25c = 2660
a = 2c
35(2c) + 25c = 2660
70c + 25c = 2660
95c = 2660
c = 2660/95
c = 28 <=== there were 28 children tickets
a = 2c
a = 2(28)
a = 56 <== there were 56 adult tickets
