Respuesta :

The curved surface area of the cone is 144 cm².

What is the curved surface area?

A cone is a three-dimensional object that consists of a circular base and an vertex.

curved surface area = πrl

Where:

  • r = radius = diameter / 2 = 6/2 = 3 cm
  • l = slant height
  • π = 3.14

3.14 x 3 x 23 = 144 cm²
