Area = 0.5*10*12 = 60 square cm
Area = 0.5*(3.5+5.5)*12 = 54 square cm
Area = 1/2*9*12 = 54 square cm
Diameter = 12 cm so radius = 6 cm. Then area = pi*r2 = 36*pi = 113.1 cm2

Area = 0.5*10*12 = 60 square cm
12 cm
12*6.5 = 78 square cm
It is: 17*12 = 204 square cm
Area = 0.5*(3.5+5.5)*12 = 54 square cm
It is 12*5 = 60 square centimetres.
It is 12*12*6 = 864 square cm
113.1 square cm
Area = 1/2*9*12 = 54 square cm
Diameter = 12 cm so radius = 6 cm. Then area = pi*r2 = 36*pi = 113.1 cm2
20 cm * 11 cm * 12 unspecified units will have a surface area of 440 cm2 + 744 cm*unspecified units.
