Answer:
Quadrilateral as it is a four-sided ploygon, having 4 edges and corners
Answer: r = 11
Step-by-step explanation:
We know that the point (-2, r) lies on the graph of:
2*x + y = 7.
Then, if we that point is on the graph of the equation, we can replace the values and we will have:
2*(-2) + r = 7
and now we solve this for r-
-4 + r = 7
r = 7 + 4 = 11
r = 11
This creates a cone! :) the formula for volume of it is 1/3 pi R^2 (h) just in case!
