Answer

88π cm³

Explanation

Given:

Radius, r = 4 cm

Height, h = 7 cm

What to find:

The surface area of the cylinder.

Step-by-step solution:

The surface area of the cylinder is given by;

[tex]S.A=2\pi rh+2\pi r^2[/tex]

Putting the values of the parameters we have

[tex]\begin{gathered} S.A=(2\times\pi\times4\times7)+(2\times\pi\times4^2) \\ \\ S.A=56\pi+32\pi \\ \\ S.A=88\pi\text{ }cm^2 \end{gathered}[/tex]
