There's this problem i've been working on for ages and i still haven't gotten it right lol.

Teh Circumference of a circle is 16 pi inches! Find the radius of the circle and the area of the circle!!!!! Then find the volume of a circular cylinder 5 inches tall that has this circle as its base!!!!!!!!!!!!!!!!!!!!!!

makes no sense!!

\(\displaystyle C = 2\pi r\)

\(\displaystyle 16\pi = 2\pi r\)

so ... what does r = ?

once you find out, substitute it for r in the formula below to find the circle's area.

\(\displaystyle A = \pi r^2\)

Reason it makes no sense is evidently because you skipped most
of your classes, or were not listening to your teacher.
If you cannot solve: 16 pi = 2 pi r
then you need more help than what is available here.

Can you solve this for x?
6a = 3ax
