I am doing a math project. I am very confused on how to find the surface area of a cone. I have looked at other equtions but i still don't understand. How do you find the surface area of a cone that has a 15cm length and a 3.5cm radius? |
Hi Cari,
Look at what Walter did in response to an earlier question. Try it with your numbers. Use Pythagoras theorem to find L and use the fact that the radius you have is 3.5 cm where Walter used 5 cm. Let us know if you still have difficulty finding the surface area.
