Question:

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)

Options:

53 cm

56 cm

64 cm

48 cm

Correct Answer:

53 cm

Explanation:

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
