Question

Find the curved surface and whole surface area of a cylinder whose radius is

14 cm

and height is

1 m

.

Accepted Answer

Given,

Radius of the cylinder $= 14 cm$ .

Height of the cylinder $= 1 m = 100 cm$ .

We know that curved surface area $= 2 π r h$ , where $r$ is the radius and $h$ is height of the cylinder.

Thus, we get

$2 \times π \times 14 \times 100$

$= 2 \times \frac{22}{7} \times 14 \times 100$

$= 2 \times 22 \times 200$

$= 8800 {cm}^{2}$

So, the curved surface area of given cylinder is $8800 {cm}^{2}$ .

We also know that whole surface area $= 2 π r h + 2 π r^{2}$ , where $r$ is the radius and $h$ is the height.

Thus, we get

$(2 \times π \times 14 \times 100) + (2 \times π \times 14 \times 14)$

$= (2 \times \frac{22}{7} \times 14 \times 100) + (2 \times \frac{22}{7} \times 14 \times 14)$

$= 8800 + 1232$

$= 10032 {cm}^{2}$

Hence, the curved surface area is $8800 {cm}^{2}$ and whole surface area is $10032 {cm}^{2}$ .

Find the curved surface and whole surface area of a cylinder whose radius is $14 cm$ and height is $1 m$ .
