Given:


\begin{gathered} \text{height(h)}=40\operatorname{cm} \\ \text{diameter(d)=28cm} \end{gathered}
\begin{gathered} \text{radius(r)}=(d)/(2) \\ \text{radius(r)}=(28)/(2) \\ \text{radius(r)}=14\operatorname{cm} \end{gathered}
\text{Total surface area=2}\pi(r)(h+r)
\begin{gathered} \text{Total surface area=2}*(22)/(7)*14*(40+14) \\ \text{Total surface area=}2*22*2*54 \\ \text{Total surface area=}4752cm^2 \end{gathered}
