Ok Melody thank you and CPhill ! You can put a check mark :)
\(a^2+b^2=c^2\)
5.6^2+3.58^2 = 44.1764
\(c^2=44.1764 \)
\(c= sqrt(44.1764) =6.6465329307842897\)
it is an analog clock
thanks CPhill and Guest !
i think:
circumference(perimetr) of a circle is 2pi r
2r=diametr
so: 60pi*100=18849.5559215387594308
aprox. aswer: 18849.6
