Answer


36\pi cm^2

Explanations:

The formula for calculating the surface area of a cone is expressed as;


SA=base\text{ area}+curved\text{ surface area}

Given the following


\begin{gathered} base\text{ area}=16\pi cm^2 \\ side\text{ area}=20\pi cm^2 \end{gathered}

Take the sum


\begin{gathered} TSA=16\pi+20\pi \\ TSA=36\pi cm^2 \end{gathered}

Hence the total surface area of the cone is 36pi square cm
