Question

The curved surface area of cylinder whose radius of the base and height are equal to 1 unit is ?

Answer 1

Answer:

2π unit²(hope I am correct)

Step-by-step explanation:

Csa of cylinder = 2πrh

Radius = height = 1 unit

⇒CSA of cylinder = 2×π×1×1 = 2π unit²

HOPE IT HELPS

Answer 2

The curved surface area of cylinder (CSA) = 6.28 square units

Step-by-step explanation:

Given,

The radius of cylinder (r) = The height of cylinder (h) = 1 unit

To find, the curved surface area of cylinder = ?

We know that,

The curved surface area of cylinder (CSA) = $2\pi rh$

= 2 × 3.14 × 1 × 1 square units

= 6.28 square units

∴ The curved surface area of cylinder (CSA) = 6.28 square units
