Is a circle with a area of 40 more less or same than a circle with a radius of 4?
In order to even discuss this question, we must assume that
the unit of the '40' is the square of the unit of the '4'.
-- The radius, diameter, and circumference of the circle with an
area of 40 are each
10.794% shorter than the corresponding measurement in the circle
with radius = 4 .
-- Its area (40) is 20.423% less than the area of the circle
with the radius of 4 .
