Largest circle

If the largest possible circle is cut off from a 8 cm × 4 cm rectangle, what is the area in sq cm of the remaining portion?

Correct answer:

S2 =  19.43 cm2

Step-by-step explanation:

a=8 cm b=4 cm  D=min(a,b)=min(8,4)=4 cm r=D/2=4/2=2 cm  S=a b=8 4=32 cm2 S1=π r2=3.1416 2212.5664 cm2  S2=SS1=3212.5664=19.43 cm2
