Answer :

The surface area of the cone is 36π

How to find the surface area of a cone?

Surface area of a cone = πr(r + l)

where

  • r = radius
  • l = length

Therefore,

r = 4cm

l² = 4² + 3²

l² = 16 + 9

l = √25

l = 5 cm

Hence,

r = 4 cm

l =  5 cm

Surface area of a cone = π(r + l)

Surface area of a cone = 4π(4 + 5)

Surface area of a cone = 4π(9)

Surface area of a cone = 36π
