Answer 2

Answer:

• The lateral surface area of the cylinder is 251.42 cm².

Step-by-step explanation:

Given that:

• A cylinder has base radius 4 cm and height 10 cm.

To Find:

• Find its lateral surface area?

Formula used:

• C.S.A = 2πRh

Where,

• C.S.A = Lateral surface area of a cylinder
• π = The value of pi is 22/7
• R = Radius
• h = Height

Finding the lateral surface area:

⇢ C.S.A = 2 × 22/7 × 4 × 10

⇢ C.S.A = (2 × 22 × 4 × 10)/7

⇢ C.S.A = 1760/7

⇢ C.S.A = 251 (approx.)

Hence,

• The lateral surface area of the cylinder = 251.42 cm²
