If a cone's radius and slant height are halved, then how will the new surface area compare to the old surface area?
Simplify your answer and write it as a proper fraction or as a whole or mixed number.
The new surface area will be _____ times the old surface area.
:
Total surface area formula
where
r = the radius
s = the slant height
:
let the original cone be 2r and 2s, half would be just r and s
cancel pi*r, then cancel (s+r)
= = = of the old surface area
