Question

Find the curved surface area of a cylinder of height 7 cm and radius 5 cm?​

Answer 1

Step-by-step explanation:

Given that:

The height of cylinder is 7cm its radius is 5cm

To find:

its Total surface area and Curved surface area.

Solution:

• The height of cylinder is 7cm
• The radius of cylinder is 5cm
• The curved surface area is 2πrh.

Known,

$= > 2 \times \frac{22}{7} \times 5 \times 7 \\ = > 220 {cm}^{2}$

The total surface area is 2πrh+2πrh²

=>

$220 + 2 \times \frac{22}{7} \times 25 \\ = > 220 + 157.14285 \\ = > 377.14285 {cm}^{2}$

So,the total surface area and Curved surface area is

$\fbox{${{\mathrm{377}}{\mathrm{.}}{\mathrm{14285}}\hspace{0.33em}{cm}^{2}}$}$ Ans.
