The slant height of a cone is 10 cm and the radius of its base is 7 cm. What is its curved surface area?
Answer :
We have
Given: slant height of the cone, l = 10 cm
Radius of the base of the cone, r = 7 cm
We need to find curved surface area of this cone.
Curved surface area of the cone is given by
CSA = πrl
Substituting the given values in the above equation,
CSA = 22/7 × 7 × 10
⇒ CSA = (22 × 7 × 10)/7
⇒ CSA = 220
Thus, curved surface area of cone is 220 cm2.
