The height of a cone is 16cm and the base radius is 12cm. Find its curved surface area.

r = 12 cm

h = 16 cm

s = 20 cm

V = 2412.74 cm³

L = 753.982 cm² <-Answer

B = 452.389 cm²

A = 1206.37 cm²

Agenda:

r = radius

h = height

s = slant height

V = volume

L = lateral surface area

B = base surface area

A = total surface area

π = pi = 3.14159

√ = square root

Lateral surface area of a cone: L = πrs = πr√ (r ² + h²)
