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
3.5 in.
1. The scale factor of the larger to the smaller is
Sor
2. The surface area will change by the square of the
scale factor, which is
3. Let the surface area of the larger cone be x.
Then, the proportion is = 11
4. Solve for x and round to the nearest hundredth.
The surface area of the larger cone is about
inches
