Question

find the curved surface area of cylinder having radius 2 cm and height is 5 cm​

Answer 1

Answer:

$\large\boxed{\sf{62.8\;{cm}^{2}}}$

Step-by-step explanation:

Given a cylinder.

Dimensions are given as :

• Radius, r = 2 cm
• Height, h = 5 cm

Now, to find the curved surface area.

We know that, curved surface area of a cylinder having radius 'r' and height 'h' is given by 2πrh.

Therefore, we will get,

=> csa = 2π × 2 × 5

=> csa = 2π × 10

=> csa = 20π

=> csa = 20 × 3.14

=> csa = 2 × 31.4

=> csa = 62.8

Hence, required curved surface area is 62.8 sq. cm.

Answer 2

Answer:

Here's your answer》》》》》》》

Step-by-step explanation:

Radius = 2cm

Height = 5cm

Curved surface area = 2(pi)×r×h

= 2 × 22/7 × 2 × 5

= 62.875 sq.cm
