Question

Please help me solve and show the steps so I could understand

Answer 1

Given polygon with sides 8 and radius 10yd.

Formula for area of ploygon

`=n* r^2* tan\left((\pi)/(n)\right)`

So, solving further

`\begin{gathered} =8*10^2* tan((\pi)/(8)) \\ =800*0.414 \\ =331.37 \end{gathered}`

Hence, 331.37 yd square is the area of polygon.
