Answer:
∫₋₃¹ π y⁴ dy
Step-by-step explanation:
If we slice the solid shape, we get circular cross sections or disks. The thickness of each disk is dy. The radius of each disk is x. So the volume of each disk is:
dV = π r² h
dV = π x² dy
Since x = y²:
dV = π y⁴ dy
The total volume is the sum of all the disks from y=-3 to y=1.
V = ∫ dV
V = ∫₋₃¹ π y⁴ dy
Answer:
is a polynomial
Step-by-step explanation:
a polynomial is a set of numbers with multiple terms that are not simplify able
is not a polynomial because its actually one term, there is no addition/subtraction of different terms.
-13 is a single number, so not a polynomial
13x^-2 is also a single number, not a polynomial
