Given:
The surface area of a right circular cone is 32 sq. cm.
Scale factor for enlargement = 3
To find:
The surface area of the new cone.
Solution:
We know that enlargement of a shape forms a similar shape and area of the similar shapes is proportional to the square of their corresponding sides.
Let the surface area of new cone be A and r be the radius of original cone
By cross multiplication, we get
The surface area of the new cone is 288 sq. cm.
Therefore, the correct option is C.
