find the surface area of the cone. use 3.14 for pi it has a base diameter of 8in and a height of 7in

can you show me how to do it I don't need the answer.

google is your friend. It gives lots of examples.

the surface area of a cone consists of its base (a circle) and its lateral area.
The lateral area is pi * r*s where s is the slant height.
I'm sure your text has several examples of this, too...
