Question

LSA of a cylinder whose circumference is 44cm and height 10 cm is​

Answer 1

circumference = 44 cm

or 2 * pie * r = 44

Lateral surface area of cylinder = 2 * pie * r * h

= 44 * 10 [since 2 * pie * r = 44]

= 440 cm2

Answer 2

Answer:

Step-by-step explanation:

Lateral surface area = The area of the sides of an object excluding the sides.

In this case it is the curved surface area of the cylinder.

The curved surface area of the cylinder is given by :

Curved surface area of the cylinder = 2πrh

2πr = The circumference of the cylinder.

in our case :

2πr = 44 cm

h = 10 cm

The Lateral Surface area = 44 × 10 = 440 cm²
