Answer:
220 cm²
Explanation:
Slant height of cone ( l ) = 10 cm
Base radius ( r) = 7 cm
CSA of cone = πrl sq.units
= 22/7 × 7 × 10
= 22 × 10
= 220 cm²
Therefore the curved surface area of cone is 220 cm².

Answer:
219.8 cm square
Step-by-step explanation:
Given : slant height is 10 cm and base radius is 7cm
To Find: find the curved surface area of a right circular cone
Solution:
Formula of curved surface area of cone =
Where r is radius and l is slant height
Since we are given slant height is 10 cm and base radius is 7cm
So, Curved surface area of cone =
=
Hence the curved surface area of cone is 219.8 cm square
