Homework Statement
The region R enclosed by the coordinate axes and the graph of y = k(x-2)^2 is shown above. When this region is revolved around the y - axis, the solid formed has a volume of 8*pi cubic units. What is the value of k?
A) 1
B) 4/3
C) 3/pi
D) 2
E) 3
Homework Equations
V = 2*pi f a -> b x [ f(x) - g(x) ] dx
The Attempt at a Solution
Ok so I pluged in 8 pi in for volume and the function for f(x) and o for g(x) and tried solving it.
After simplifying I got 4 = 8/3k
and for k I got 12/8
But that is not an answer choice.
Can I get some help, I would really appreciate it!
Thank You very much!
