Detailed Solution
Download Solution PDFGiven:
Diameter of the base (d) = 28 cm
Radius (r) = d/2 = 28/2 = 14 cm
Height (h) = 42 cm
Formula used:
Curved Surface Area (CSA) of a cylinder = 2πrh
Calculations:
CSA = 2 × π × 14 × 42
⇒ CSA = 2 × 22/7 × 14 × 42
⇒ CSA = 2 × 22 × 2 × 42
⇒ CSA = 3696 cm2
∴ The correct answer is option (4).
