Question

Circumference of a cylinder
is 22cm and its
height 10 cm. Hence its curved surface
area​

Answer 1

Given:-

•Circumference of a cylinder=22cm

•Height of the cylinder=10cm

To find:-

•Curved surface area of the cylinder

Solution:-

We know that curved surface area of a cylinder is ----

$= > 2\pi r h$

$= > (22 \times 10) {cm}^{2}$

$= > 220 {cm}^{2}$

Thus,curved surface area of the cylinder is 220cm².

Answer 2

Step-by-step explanation:

Circumference of a cylinder=22cm

•Height of the cylinder=10cm

To find:-

•Curved surface area of the cylinder

Solution:-

We know that curved surface area of a cylinder is ----

= > 2\pi r h=>2πrh

= > (22 \times 10) {cm}^{2}=>(22×10)cm

2

= > 220 {cm}^{2}=>220cm

2

Thus,curved surface area of the cylinder is 220cm².
