Chapter 0, Problem 57PO

To determine

The surface area of the cylinder.

Answer to Problem 57PO

  $A=345.4{\text{ cm}}^2$

Explanation of Solution

Given:

Height $h=6$ cm

Radius $r=5$ cm

Formula used:

Surface of cylinder,

  $A=2\pi r^2+2\pi rh$

Where,

  $r=$ Radius

  $h=$ Height

Calculation:

Surface of cylinder,

  $\begin{array}{l}A=2\pi r^2+2\pi rh\\ A=2\pi {\left(5\right)}^2+2\pi \times 5\times 6\\ A=345.4{\text{ cm}}^2\end{array}$

Nearest tenth is 345.4.

Conclusion:

Hence, the surface area of the cylinder is $345.4{\text{ cm}}^2$ .
