Answer:
The correct answer is B.
Step-by-step explanation:
In this graph we can see a "Parabola", this is the curve for a second degree polynomial function, and based on "Fundamental theorem of algebra" we can know that this polynomial has 2 roots (they can be real or imaginary).
In this graph, the curve doesn't touch the X axis, so we know that this function has not real root. So both roots are complex

Answer:
a) 16
b) Using is more accurate because it represents the exact and full value of pi, rather than an estimation or approximation like 3.14.
Step-by-step explanation:
The formula to find the volume of a cone is . We know the radius is 6, so all we need to find is the height, h. By using the Pythagorean theorem, we can see that the height is , or 8. Plugging in all the values into the formula gives us:
V =
V = 16
