Respuesta :

The total surface area of the cone is 3π + 10 cm².

What is the curved surface area?

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

Total surface area = πr (r + l)

Where:

  • r = radius
  • l = slant height
  • π = pi

π x 3 + (3 + 7)

3π + 10 cm²
