Circumradius of Pentagon given Height using Interior Angle Solution

Follow our step by step solution on how to calculate Circumradius of Pentagon given Height using Interior Angle?

FIRST Step Consider the formula

r c = \frac{h}{\frac{3}{2} - \cos (\frac{3}{5} \cdot π)}

Next Step Substitute values of Variables

∴

r c = \frac{15m}{\frac{3}{2} - \cos (\frac{3}{5} \cdot π)}

Next Step Substitute values of Constants

∴

r c = \frac{15m}{\frac{3}{2} - \cos (\frac{3}{5} \cdot 3.1416)}

Next Step Prepare to Evaluate

∴

r c = \frac{15}{\frac{3}{2} - \cos (\frac{3}{5} \cdot 3.1416)}

Next Step Evaluate

∴

r c = 8.29179606750063m

LAST Step Rounding Answer

∴

r c = 8.2918m
