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
