The circumference of a 12-foot-diameter circle is 37.7 feet.
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 .
Circumference of any circle = 2*pi*radius or diameter*pi

Oh, dude, you're hitting me with some math here. So, the circumference of a circle is calculated by multiplying the diameter by pi (π). Since the diameter of a circle is twice the radius, and you've given me the radius (40 mm), I can tell you that the circumference of a 40 mm circle would be approximately 251.2 mm. It's like math, but with a side of sarcasm.
The circumference of a 12-foot-diameter circle is 37.7 feet.
That depends on what the 40 foot represents but in general the area of a circle equals pi times radius squared.
127.324 square units correct to 3 decimal places
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 .
By definition pi is the ratio between the circumference and the diameter pi=C/D so C=pi*D and C=pi*40=125.6 (if pi=3.14)
The circumference of a circle, if the diameter is 40 inches, is about 125.7 inches. (C = d x Pi).
Circumference of any circle = 2*pi*radius or diameter*pi
It is impossible to answer the question because the circumference cannot be 40 degrees.
The radius of a circle whose circumference is 40pi is 20 units.
