Choose the correct option: 

A solid right circular cylinder has a radius of 14 cm and a height of 8 cm. Its total surface area is ____ cm².

Given,

The radius of the cylinder, r = 14 cm
height, h = 8 cm
The total surface area of the cylinder = $=2\mathrm{\pi }r\left(h+r\right)$

$$\begin{gathered} =2\times \frac{22}{7}\times 14\times \left(14+8\right) \\ =2\times 22\times 2\times 22 \\ =1936 {\mathrm{cm}}^2 \end{gathered}$$

Therefore, the total surface area of the cylinder = 1936 cm²
