Aregion r is revolved about the x-axis. the volume of the resulting solid could (in principle) be found by using the disk/washer method and integrating with respect to ▼ x y or using the shell method and integrating with respect to ▼

Solution in explanation given below.

Step-by-step explanation:

Consider a region R revolved about the x-axis

The volume of the resulting solid using the shell method is given by:

V =

where p(y) ≥ q(y) for c ≤ y ≤ d

Hence, the solutions of the answers are filled with x and y respectively.

the answer would be the last one (constat) she stays at the same rat every two mintues it goes up by 0.4

step-by-step explanation:

the answer will be b x² +x-1
