Answer:
Required volume is unit.
Step-by-step explanation:
Given equations of curves,
,
substitute second in first we will get,
When and . Thus both curves intersect at the points (4,16),(-4,16). And thus .
Considering width of the representative rectangle as which is parallel to x-axis because of considering cylindrical shell. Therefore volume of the shell is given by,
Now,
Length of generating box=Length of from line x=4(axis of revolution)=circumference of the shell=(4-x)
Width of box=
Hence,
which is required volume of generating area.
Answer:
Step-by-step explanation:
36/24 or 3/2
<u>Answer:</u>
W (-1, 4) ---> W' (-4, -1)
X (-1, 2) ---> X' (-2, -1)
Y (2, 2) ---> Y' (-2, 2)
Z (2, 4) ---> Z' (-4, 2)
<u>Step-by-step explanation:</u>
We have with a rectangular figure WXYZ and we are to find the coordinates of its vertices W'X'Y'Z' after the transformation of 90° rotation.
We know that, the rule for 90° rotation of a point (x, y) gives (-y, x).
So,
W (-1, 4) ---> W' (-4, -1)
X (-1, 2) ---> X' (-2, -1)
Y (2, 2) ---> Y' (-2, 2)
Z (2, 4) ---> Z' (-4, 2)
