Question

if the curved surface area of right circular cylinder of radius is 7 cm is 440 cm²,then find the height of the cylinder​

Answer 1

Answer:

$2 \times \frac{22}{7} \times 7cm \times h = 440 {cm}^{2}$

$h = \frac{440 {cm}^{2} \times 7 }{2 \times 22 \times 7cm}$

$h = 10cm$

Answer 2

Step-by-step explanation:

The volume of the cylinder is 1540 cubic centimeter.

Given: Curved surface area of right circular cylinder is 440 cm² and the radius of its circular base is 7 cm.

To find : The volume of the cylinder ?

Solution :

The radius of cylinder is r-7 cm

Curved surface area of right circular cylinder is 440 cm².

CSA = 2pi * r * h

440 = 2 * 22/7 * 7 * h

h = 440/(2 * 22)

h = 10

The height is 10 cm.
