Answer: A

explanation: when it said there are 9 more children than parents in a room, it doesnt say the amount of parents, nor children, so its mainly saying that theres just more children than parents, so we mainly need to find out how many parents, and then add the amount of children, so it would most likely be A. here's how to answer the question, we need to find 2 numbers that would add up to 25, and one of the numbers has to be made with a 9 and another number, getting straight to the point, the other number would be 8, so there would be 8 parents, and 8 children, but if theres 9 more children than parents, it would be 8 + 9, which is 17, meaning that there is 17 children, then you add the amount of parents, which is 8, to 17, which adds up to 25, which is the max amount of people in the room, so the amount of children is 17, and the amount of parents is 8, If you weren't to have done that, the unknown would've been the total number of children and the total number of parents in the room.

Answer:

$V=176\pi\ in^3$

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

The given figure is in the shape of a cylinder

so

To find out how much grain can this container hold, determine the volume of the cylinder

The volume of the cylinder is given by the formula

$V=\pi r^{2} h$

we have

$r=4\ in\\h=11\ in$

substitute

$V=\pi (4)^{2} (11)$

$V=176\pi\ in^3$
