The answer it is It’s the last one

Surface area of cone2 is equals to 96π.

What is surface area?

"Surface area is defined as the sum of the area of all the faces of given three dimensional shape."

Formula used

Surface area of the cone = πr² + πr l

According to the question,

Given,

'r' represents the radius of the cone

'h' represents the height of the cone

'l' represents the slant height of the cone

Cone1 and Cone2 are congruent cones.

⇒Radius of cone1 = Radius of cone2

  Slant height of cone1 = Slant height of cone2

As per the given dimensions we get,

Radius of both the cones 'r' = 6units

Slant height of both the cones 'l' = 10units

Substitute the values in the formula we get,

Surface area of the cone2 = π (6)² + π (6) (10)

                                            = 36π +60π

                                            = 96π square units

Hence, surface area of cone2 is equals to 96π.
