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.
The slope is 0!! any horizontal line, like y = 1, y = 2, y = any other number, has a slope of 0. because it's a horizontal line, it's flat, so there isn't any incline or decline. just as a note: vertical lines (x = 1, etc.) have an undefined slope.
