The two cones are similar. the smaller cone has a
surface area of 11.74 inches
complete the last step to determine the surface area of
the larger cone.
1. the scale factor of the larger to the smaller is
or
lo
cl
in
si
2. the surface area will change by the square of the
scale factor, which is or
let the surface area of the larger cone bex
then, the proportion is 2 = 11.74
4 solve for x and round to the nearest hundredth
the surface area of the larger cone is about
inches?
