Marks: +1, -0

The curved surface area of a cone is 4070 sq. cm. If the diameter of the base of that cone is 70 cm, then its slant height in centimeters is

Solution:

CSA : Curved surface area of cone = π(radius) × (Slant height)
∴ Slant height

=\text "CSA"/\text "π(radius)"

=4070/{22/7×(70/2)}=37
