Company logo

The company logo consists of a blue circle with a radius of 4 cm, which is an inscribed white square. What is the area of the blue part of the logo?

Correct result:

S =  18.2655 cm2


r=4 cm u=2 r=2 4=8 cm D=u=8=8 cm  D2=a2+a2  a=D/2=8/2=4 2 cm5.6569 cm  S1=π r2=3.1416 4250.2655 cm2 S2=a2=5.65692=32 cm2  S=S1S2=50.265532=18.2655 cm2
