Surface area of cone is square units

Solution:

Given that cone with a slant height of 7 and a radius of 2

To find: surface area of cone

The surface area of a cone is equal to the curved surface area plus the area of the base

The surface area of cone is given by formula:

Where "r" is the radius and "l" is the slant height of cone

Substituting r = 2 and l = 7 in above formula,

Thus surface area of cone is square units
