F is sometimes Positive and sometimes negative on the interval
which means the parabola
intersects the x-axis at
and
. Assume
.
Then the volume of the solid generated by revolving the region about the x-axis is
Revolving about the y-axis, the volume would be
The volumes are the same independent of which axis is taken as the axis of revolution, so
We're assuming
, so we can safely divide both sides by
to get
.
Answer:
Total Area = 532 m²
Step-by-step explanation:
Triangle = ½bh.
Rectangle = lw.
Total Area = sum of individual areas =
(8 m × 16 m) / 2 + (16 m × 18 m) / 2
+ (18 m × 18 m) =
(64 m²) + (144 m²) + (324 m²) =
532 m²
Answer:
48
Step-by-step explanation:
remember 1 dozen of something is 12 of that object
so 1 dozen cookies is 12 cookies
two dozen means two times one dozen
or 2-times twelve (because there are twelve of an object in a dozen)
2 times 12 is 24
now you double the recipe that makes 2 dozen cookies
so you have 24 cookies and you multiply that by 2 to double it and you get 48
