Answer:
The answer is option A
Step-by-step explanation:
[tex] \frac{4\pi \sqrt{5} - 2\pi \sqrt{5} }{3 \sqrt{5} } [/tex]
Simplify the numerator first
Since they have the same square root that's root 5 we can subtract them directly
That's
[tex]4\pi \sqrt{5} - 2\pi \sqrt{5} = (4\pi - 2\pi) \sqrt{5} \\ = 2\pi \sqrt{5} [/tex]
So we have
[tex] \frac{2\pi \sqrt{5} }{ 3\sqrt{5} } [/tex]
Reduce the expression with √5
We have the final answer as
[tex] \frac{2\pi}{3} [/tex]
Hope this helps you
