What is the surface area of a cone in inches when the slant height is 6 inches and the diameter is 4 inches

Answer»

Answer:

Total surface AREA of a cone:

A = L + B

   = πrs + πr^2

    = πr(s + r)

     = πr(r + √(r^2 + h^2))

Radius         r = 2 in

HEIGHT         h = 5.6 in  (approximately)

SLANT height s = 6 in

Total surface area      A = 50.26 in^2 (approximately)
