(2009? Jinan) In the comprehensive practical activity class, Xiaoming made a cone funnel model with cardboard. As shown in the figure, its bottom radius is OB=
OB = 6，OC=8，
∴BC=OC2+OB2= 10cm，
The circumference of the cone bottom is 2π×6= 12πcm.
The lateral area of this funnel is s =12× BC×12 π = 60 π (cm2).
So choose C.
