Answer:
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√(r² + h²)
