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

x^{2}+y^{2}+16

2. Relevant equations

[tex]\pi[/tex][tex]\int^{b}_{a}[/tex]{R(x)^{2}}dx

3. The attempt at a solution

I just need to know if i set this up right.

When I solve for y and graph it I get a semi circle that goes from -4 to 4.

[tex]\pi\int^{0}_{-4}[/tex]{([tex]\sqrt{(16-x^{2})}[/tex])[tex]^{2}[/tex]}dx + [tex]\pi\int^{4}_{0}[/tex]{([tex]\sqrt{(16-x^{2})}[/tex])[tex]^{2}[/tex]}dx

I get 85.4[tex]\pi[/tex]
