Radius (r) = 5 cm
Slant height (l) = 16 cm
Formula used:
Total surface area of cone = πr(r + l)
Where, π = 22/7
Calculation:
Total surface area = (22/7) × 5 × (5 + 16)
⇒ Total surface area = (22/7) × 5 × 21
⇒ Total surface area = (22 × 5 × 21)/7
⇒ Total surface area = (2310)/7
⇒ Total surface area = 330 cm2
∴ The correct answer is option (3).
