Question

A cylinder has length of 28 m and diameter 5 cm. Find its total surface area.A) 1.1 sq.mB) 2.2 sq.mC) 4.4 sq. m.D) None of these

plss help​

Answer 1

Answer:

Length or height of cylinder => 28 m

Diameter of cylinder => 5 cm

∴ Radius => 5/2 cm = 2.5 cm

Now, we will convert Radius from centimeters (cm) to meters (m) :-

Radius => 2.5 × 1/100 m

=> 0.025 m

Curved surface area (CSA) => 2πrh

=> (2 × 22/7 × 0.025 × 28) m²

=> 4.4 m²

Hence, the answer is 4.4 m²

Step-by-step explanation:

Option (C) is correct.
