the slant height (s) is ... s^2 = √[(8/2)^2 + 3^2]
... s is the radius of the circle the cone was made from
the area of the source circle is ... π s^2
the circumference of the source circle is ... 2 π s
the circumference of the cone base is ... 8 π
the curved surface area of the cone is ... [(8 π) / (2 π s)] * π s^2
... s is the radius of the circle the cone was made from
the area of the source circle is ... π s^2
the circumference of the source circle is ... 2 π s
the circumference of the cone base is ... 8 π
the curved surface area of the cone is ... [(8 π) / (2 π s)] * π s^2
