Answer: 50.2

Step-by-step explanation:

Volume of Cone = pi(r)^2 h/3

3.14 * r * r * h/3

2 * 2 = 4

3.14*4*h/3

h/3 = 12/3 = 4

3.14 * 4 * 4 = 50.24 Rounded, this is 50.2

There were 166 paid admissions to a game. The price was $2 for adults and $.75 for children. The amount of data taken in was $29
JulijaS [17]

Answer:the number of adults that attended the game is 135.

the number of children that attended the game is 31

Step-by-step explanation:

Let x represent the number of adults that attended the game.

Let y represent the number of children that attended the game.

There were 166 paid admissions to a game. This means that

x + y = 166

The price was $2 for adults and $.75 for children. The amount of data taken in was $293.25. This means that

2x + 0.75y = 293.25 - - - - - - - - - - 1

Substituting x = 166 - y into equation 1, it becomes

2(166 - y) + 0.75y = 293.25

332 - 2y + 0.75y = 293.25

- 2y + 0.75y = 293.25 - 332

- 1.25y = - 38.75

y = - 38.75/- 1.25

y = 31

x = 166 - y = x = 166 - 31

x = 135
