Step-by-step explanation:
The answer is A) √3
cot(-5π/6)=1/tan(-5π/6)
=1/tan(-(5π/6)
Use the property: tan(-x)=-tan(x)
=1/tan(5π/6)
-(1/tan(5π/6))
tan(5π/6)=-√3/3
-(1/-√3/3)
-(1/-√3/3)
=√3
1/3•3.14•. r^2 •h
1/3•3.14•20^2•25
10466.6667
that rounds up to 10,467.
I could be wrong though!
hope this helps! :)
