The ratio of the number of linear units in the circumference of a circle to the number of square units in the
area of that circle is 2:5.What is the radius of the circle?
正解:
5
Explanation/Reference:
The circumference of a circle = 2(Pi)r and the area of a circle = (Pi)r2. If the ratio of the number of linear units
in the circumference to the number of square units in the area is 2:5, then five times the circumference is
equal to twice the area:
The radius of the circle is equal to 5.
