The curved surface area of a right circular cone of radius 28 cm is 4664 cm2 . What is the slant height of the cone?(Use π=22/7)
Answer & explanation
Correct answer: option 1
We know that ,
Curved surface area of cone = π × Radius × Slant height
4664 = \(\frac{22}{7}\) × 28 × Slant height
Slant height = 4664 × \(\frac{7}{22}\) × \(\frac{1}{28}\)
= 53 cm
