No, no it can't. Circumference = 2r*pi Area = pi*r2 For the area to equal the circumference pi*r2 = pi*2r so divide both sides by pi r2 = 2r so divide both sides by r r = 2 Note that circumference is in units and area is in units squared i.e. radius = 2m, area = 12.56637m2 Ciercumference = 12.56637 m

What is the outside of a circle known as?
Oh, dude, the outside of a circle is called the circumference. It's like the circle's boundary or edge, you know? So, if you're ever lost in a circle, just look for the circumference to find your way out.
What is the best estimate of the circumference of a circle 2 units?
The Circumference of a circle (C) equals the number "pi" times the diameter of the circle (d). "pi" (3.14159...) is a number which you can never find the value of precisely, the numbers after the decimal point go on for ever. Given this information you can calculate what you need to know about your circle.
What should the value of pi be in taxicab geometry?
The value of pi in taxicab geometry technically does not exist as any taxicab shape would consist of right angles. A circle does not contain any right angles, therefore circles do not exist in taxicab geometry (so neither does the value pi).However, if you were to place a square around a circle with diameter 1, where each side is a tangent to the circle and then removed the corners of the square repeatedly without ever removing any or the area of the circle (see Figure 1), the value of 'pi' in that case would be 4 (as pi = diameter/circumference (or in this case perimeter)).Figure 1Here the problem arises, as perimeter and circumference are not exactly the same thing. Circumference only pertains to a circle (and circles do not exist in taxicab geometry) whereas perimeter pertains to any geometric shape (whether in taxicab geometry or Euclidean geometry).
Does pi equal 3.14?
Pi is ROUNDED to 3.14. Pi really goes on for ever and ever.
How do you calculate the circumference of a balloon?
Balloons are rarely (if ever) spherical, so you need to decide what you mean by its circumference.On possible way is to make a slip-knot noose with a piece of string. Slide the noose over the balloon, keeping the string tight. The noose will be opened to the extent of the balloon's circumference.
