About 6,000 Double check the answer i gave you.
1374 multiplied by 6 would be 8244
:)
For each <em>x</em> in the interval 0 ≤ <em>x</em> ≤ 5, the shell at that point has
• radius = 5 - <em>x</em>, which is the distance from <em>x</em> to <em>x</em> = 5
• height = <em>x</em> ² + 2
• thickness = d<em>x</em>
and hence contributes a volume of 2<em>π</em> (5 - <em>x</em>) (<em>x</em> ² + 2) d<em>x</em>.
Taking infinitely many of these shells and summing their volumes (i.e. integrating) gives the volume of the region:

65/100 = 13/20
(divide by 5 on both sides)
Hope this helped!
For Range you take the biggest number and subtract it with the smallest. So:
January = E14,000
Febuary = E9,000
March = E10,000
All Three Months = E17,000
Hope this helps,pleeease vote as brainliest!
