The two cones are similar. The smaller cone has a surface area of 11.74 inches2. Complete the last step to determine the surface
area of the larger cone. The scale factor of the larger to the smaller is , or . The surface area will change by the square of the scale factor, which is , or . Let the surface area of the larger cone be x. Then, the proportion is = . Solve for x and round to the nearest hundredth. The surface area of the larger cone is about inches2.
for the first 2 questions 3.04 x 10^2 you would move the decimal over 2 places and 0.304 x 10^4 just move the decimal over4 places and you have your answer
