Question

what is the curved surface area of a cylinder with length 5 m and radius 2 m? 1. 44 sq.m. 2. 440/7 sq.m 3. 440/7 cm 4. 7/440 sq.m.​

Answer 1

Answer:

• Curved surface area of the cylinder = 440/7 sq. m

Step-by-step explanation:

Given that:

• Length/Height of a cylinder = 5 m
• Radius of the base of a cylinder = 2 m

To Find:

• Curved surface area of the cylinder.

Formula used:

• Curved surface area of a cylinder = 2πrh sq. unit

Here,

• Radius is denoted as r.
• Height/Length is denoted as h.

Finding the curved surface area:

⇒ Curved surface area = 2πrh sq. unit

⇒ Curved surface area = (2 × 22 × 5 × 2)/7 sq. m

⇒ Curved surface area = 440/7 sq. m

Answer 2

Answer:

62.85 m²

Step-by-step explanation:

HEIGHT OF THE CYLINDER = 5 m

RADIUS OF THE CYLINDER = 2 m

∴ CSA (CURVED SURFACE AREA) OF THE CYLINDER = 2πrh

= 2 × 22/7 × 2 × 5

= 44/7 × 2 × 5

= 440/7

= 62.85 m²
