300 * 2 π * r = 300 * 2 * 3.14 * 1 = 1884m
2/12*100%≈16.67%
75% * 24 = 18 hours

In a circle, there is the smallest square with a side length of 2 decimeters. What is the area of the circle?

Wrong topic, it should be the largest square, then the diameter of the circle is the diagonal of the square
r^2=2^2+2^2=8
2R = radical 2
R = radical 2
Area of circle = 2 * 3.1415926
