Answer:

The slant height of the cone affected is two times the slant height of original cone

Explanation:

we know that

If the height and base radius of a cone are increased by a factor of
2 to create a similar cone

then

the scale factor is equal to
2

therefore

the slant height of the cone affected is equal to the slant height of the original cone multiplied by the scale factor

Find the slant height of the original cone

Let

l-----> slant height of original cone

la-----> slant height of the cone affected

Applying the Pythagoras theorem


l=\sqrt{h^(2) +r^(2) }

so


la=2l


la=2\sqrt{h^(2) +r^(2) }

The slant height of the cone affected is two times the slant height of original cone
