What is the area of the curved surface of a right circular cone of radius 5 and height 12?
The area is given by
pi * (cone radius) * slant height of cone =
pi * 5 * sqrt (5^2 + 12^2) =
5 * 13 * pi =
65pi units^2 ≈ 204.2 units^2
How can you do a fraction that is involved in the equation
Could you give an example????
