Question

The integral using vertical rectangles which finds the volume obtained when the region bounded by y=x and y=x^2 is rotated about the line y=1 is?

Answer 1

I got pi/5 and I just wanted to double check with someone

Answer 2

its been a while . ..

Answer 3

That's alright, I can wait :)

Answer 4

No. I cant recall this stuff well enough. I looked it up on wolfram though and pi/5 is correct.

Answer 5

Oh okay, totally forgot to use wolfram, thanks anyway!

Answer 6

yw

Answer 7

Volume generated = pi * INT [(1 - x^2)^2 - ( 1 - x)^2] dx between the limits 0 and 1
