Question

need any help with this that you guys can give. thank you

Answer 1

I'll do number 11 for you 

Area of a sector can be found using 
A = (πr²)C/360  where C is the measure of your central angle
$A = \pi (6^{2} )( \frac{75}{360} )$
A ≈ 23.56 m²

Oh, I guess rounded to the nearest tenth is 23.6
