Given the cylinder $(x-1)^2+y^2 leq1$ and a sphere centred at $(0,0,0)$ with radius $2$, find the volume of...
$begingroup$
I attempted this using cylindrical co-ordinates but I am not sure if my attempt is correct. This is what I have:
equation of sphere : $x^2+y^2+z^2=4,$ cylindrical coordinates this is $z^2=4-r^2$ leading to:
$$0.25V= int_0^{pi/2} int_0^1 rsqrt{4-r^2} ,drdvartheta$$
calculus volume

Use$pi$
for $pi$ and use$sqrt{wxyz}$
for $sqrt{wxyz}$.

This is called MathJax, a type of $LaTeX$. It works in the title section too.

It might help to include what steps you took to get your answer, since what's important when studying Mathematics is not so much the answers to questions, but the reasons why they are the answers. Again, please edit the question.
