Given:

The radius of the base of the given cone = 5 cm

The slant height of the cone = 19 cm

To find the surface area of the given cone.

Formula

The surface area pf the given cone is,


SA = \pi rl+\pi r^(2)

where, r be the radius and

l be the slant height.

Now,

Taking, r = 5, l = 19 and π = 3.14 we get,


SA = (3.14)(5)(19)+(3.14)(5^2) sq cm

or,
SA = 298.3+78.5 sq cm

or,
SA = 376.8 sq cm

Rounding off to the nearest square centimeter, we get;


SA=377 \ cm^2

Hence,

The surface area of the cone is 377 sq cm.
