This is the answer

Answer 2

Curved surface area is 440 cm².

Total surface area is 748 cm².

Volume is 1540 cm³.

Step-by-step explanation:

Given : The radius of a circular cylinder is 7 cm, its height is 10 cm.

To find : The curved surface area, total surface area and volume of the cylinder ?

Solution :

The radius is r=7 cm

The height is h=10 cm

The curved surface area of the cylinder is

$CSA=2\pi r h$

$CSA=2\times \frac{22}{7}\times 7\times 10$

$CSA=440\ cm^2$

The total surface area of the cylinder is

$TSA=2\pi rh+2\pi r^2$

$TSA=440+2\times \frac{22}{7}\times 7^2$

$TSA=440+308$

$TSA=748\ cm^2$

The volume of the cylinder is given by,

$V=\pi r^2h$

$V=\frac{22}{7}\times 7^2\times 10$

$V=1540\ cm^3$
