HELP WITH THIS MATH QUESTION

3

Step-by-step explanation:

The solution to a system of equations is the intersection point of two or more lines on a graph.

In this case, we see that at (1, 3)

Remember that this question is asking for the y intercept, not the full coordinates or the x intercept.

We know that the full coordinates are (1, 3), or (x, y), and since we need y, we know the y cooridnates are 3, not 1, since this is x.

So the first answer, A, is correct.

Hope this helps!

30+15

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
