The surface area of a right circular cone is given by:
S+=+%28pi%29Rs Where: R is the radius and s is the slant height.
S+=+%28pi%29%283%29%285%29
S+=+15%28pi%29square inches. If you use %28pi%29+=+3.14, then,
S+=+47.1square inches.
If you include the area of the base, then you add:
B+=+%28pi%29R%5E2
B+=+9%28pi%29
Total surface area:
S+%2B+B+=+15%28pi%29+%2B+9%28pi%29
S+%2B+B+=+24%28pi%29 If %28pi%29+=+3.14, then,
S+%2B+B+=+75.36 square inches.
