If you tripled the slant height and radius of a cone, what would be the formula to find the modified surface area?

Hence, the formula to find the modified surface area is:

i.e. it is 9 times the surface area of the original cone.

We know that the surface area of a cone is given by the formula:

where r is the radius of the cone and l is the slant height of the cone.

Now we have that:

The slant height of the cone is tripled and the radius of a cone is also tripled.

i.e.  r=3r

and l=3l

Hence, the modified surface area is given by:
