Answer 2

Answer:

The curved surface area of the cylinder is 100.57 m².

Step-by-step explanation:

Solution :

The dimensions of the rectangle = 8 m and 2 m

The dimensions of cylinder formed -

• Height = 8 m
• Radius = 2 m

★ Curved Surface Area of a cylinder -

⇒ 2πrh

⇒ 2 × $\sf{\dfrac{22}{7}}$ × 2 × 8

⇒ $\sf{\dfrac{44}{7}}$ × 2 × 8

⇒ $\sf{\dfrac{88}{7}}$ × 8

⇒ $\sf{\dfrac{704}{7}}$

⇒ 100.57 m² (Approx)

Therefore, the curved surface area of the cylinder is 100.57 m².
