Volume of the cone: 1/3 of area of the circle * the height
(1/3)π5²*5=(125/3)π
volume of the cylinder: area of the circle *the height: π5²*10=250π
add up: (125/3)π+(125/3)π+250π≈1047.2
D is the correct answer
Answer:
12:45
Step-by-step explanation:
Step One: An hour after 11:20 is 12:20, plus 15 minutes is 12: 35.
Step Two: Just add 10 minutes, because it doesn't matter when you add the ten minutes.

![4x - y = - 5 \\ - 2x + y = 3](https://tex.z-dn.net/?f=4x%20%20-%20y%20%3D%20%20-%205%20%5C%5C%20%20-%202x%20%2B%20y%20%3D%203)
Solve the second equation for y
![4x - y = - 5 \\ y = 3 + 2x](https://tex.z-dn.net/?f=4x%20-%20y%20%3D%20%20-%205%20%5C%5C%20y%20%3D%203%20%2B%202x)
Substitute the given value of y into the first equation
![4x - (3 + 2x) = - 5](https://tex.z-dn.net/?f=4x%20-%20%283%20%2B%202x%29%20%3D%20%20-%205)
Solve the equation for x
![x = - 1](https://tex.z-dn.net/?f=x%20%3D%20%20-%201)
Substitute the given value of x into the second equation
![y = 3 + 2( - 1)](https://tex.z-dn.net/?f=y%20%3D%203%20%2B%202%28%20-%201%29)
Solve the equation for y
![y = 1](https://tex.z-dn.net/?f=y%20%3D%201)
The possible solution of the system is the ordered pair (x,y)
![(x,y) = ( - 1, 1)](https://tex.z-dn.net/?f=%20%28x%2Cy%29%20%3D%20%28%20-%201%2C%201%29)
