you should use the ratio test. where ever the limit evaluated by ratio test is less than one the series converges

First try substituting u=4+x²⇒du=2xdx⇒(1/2)du=xdx for the substitution part that should be a lot easier . you are still heading the right direction (1/2)∫(1/(u^{1/2}))du= √u I think you can take it from here

Math I think on this specific problem you just have to use Simpson's rule in order to approximate the integral. V=2πrh for any small part of the tree considering the radius remains constant. in order to get the approximate volume you use any of the numerical methods of integration such as...
