Answer 2

Answer:

If the curved surface area of a right circular cone is 660 cm²

base radius is 10 cm

then the slant height of the cone.

$660 = \frac{1}{3} \pi \: rl$

$660 = \frac{1}{3} \times \frac{22}{7} \times 10 \times l \\ 3= \frac{1}{3} \times \frac{1}{7} \times l \\ slant \: height \: \\ l = 42 \: cm$
