(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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

2. Relevant equations

V = 2*pifa -> b x [ f(x) - g(x) ] dx

3. 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!!
