I REALLY NEED SOMEONE TO HELP ME WITH AT LEAST ONE OF THESE PROBLEMS.. PLEASE The solid is similar to a larger solid with the given scale factor, find the surface area and volume of the larger solid.cone: scale factor 3:4, SA=96pi cm^2, V=96pi cm^3

do you mean that the height and the radius are proportionally larger in the bigger cone?

okay, can you get the radius from the surface area and post it here?
anonymous
  • anonymous
how would i do that

  • anonymous
surface area = 96 so what is the radius?

what is the formula for SA of a cone? what is the formula for Volume of cone?

radius would be 4?

multiply old radius by (3/4) and plug that into equation to get new parameters of cone

If two similar solids have a scale factor of a:b then corresponding areas have a ratio of a2:b2, and corresponding volumes have a ration of a3:b3.

Surface area Surface area a2 = b2 Volume Volume a3 = b3
