They can't have the same value, since area has square units and circumference
has linear units. But their number portions can be the same.
The circumference and the area of a circle with a radius of 2 are both (4 pi), with
the appropriate units.

It cannot be because the first is a measure of length whereas the second is a measure of area. Basic rules of dimensional analyses states that such comparisons are meaningless.However, the numerical value of the circumference of a circle and the numerical value of its area will be the same if the radius has a value of 2 in some measurement units.A circle with radius of 10 cm has a circumference of 63 cm and an area of 314 cm^2 and these are clearly not equal. But if the measurements are taken in units of 5 cm, then the radius is 2 units and the circumference is 12.6 units while the area is 12.6 square units - the same numeric value.
If its diameter is 4 units in length then:- Area of circle: pi*2^2 = 4*pi square units Circumference of circle: 4*pi units
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
The value of pi is constant. It is calculated by dividing the circumference of a circle by its diameter. As the circle's circumference grows, the diameter grows at the same rate, proportionally. This means that the circumference divided by the diameter (if measured precisely) will always yield pi. If it does not, it is not a perfect circle. The ratio between the circumference and the diameter of a circle will always stay the same, no matter how you change the size of the circle.
The circumference of a circle is the same as the perimeter of a circle, so the perimeter and circumference would both be 3 ft.
