....................................
The first jar has capacity  pi (3)^2(8) = 72 pi, and 75% of that is 54 pi.

The second jar has capacity  pi (5)^2(4) = 100 pi.

54pi is 54% of 100 pi.

P.S. Don't mark PRIVATE.  I change it, anyway.  If you don't want anyone to see your question or answer, you have to send it elsewhere.
