<h2>Explanation:</h2><h2></h2>

Hello! Remember you have to write complete questions in order to get good and exact answers. I'll help you to understand this problem, but I have to assume some things.

We know that the empty cup in the shape of a cylinder is being filled with water. Suppose the volume of this cylinder is:

$V=450cm^3$

Suppose that the cup is filled at a constant rate of $s=50cm^3/s$ , so in 7 seconds the cup is filled the following amount:

$V'=50\times 7=350cm^3$

So this represents the following percentage:

$\frac{V'}{V}\times100=\frac{350}{450}\times 100=77.78\%$

Finally, after 7 seconds the cup is 77.78% filled
