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.
What does pi find?
Pi is the circumference of the circle divided by the diameter of the circle. Every circle, that ever was, is, or ever will be.
What is the circumference of a diameter with 9 yd?
The circumference of EVERY circle is (pi) times (the diameter).Now you can calculate the circumference of not only that particular circle, butalso the circumference of any other circle that you'll ever meet in the future.

What is the difference between the area and the circumference of number eight?
Do you mean the geometrical shape that is the character "8" ? If so then drawn in its simplest form as two tangential circles not necessarily of the same radii, so obviously: - the circumference of each circle will vary with its ownradius, and - the area of each circle will vary as the square of its own radius; and the combined circumference or area will be the sum of the two individual ones respectively. I can't say I've ever had to calculate areas and perimetersof characters but I suppose you might if you are in sign-making or neon-lamp manufacturing!
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.

What is the hardest geometry problem ever?
One of many is knowing the exact value of pi which is a circle's circumference divided by its diameter.
What is the circumference of a circle with radius of 6?
The circumference of a circle is (pi) x (diameter), and the diameter is (2 x radius). Now you can find not only the circumference of the circle in this question, but of any circle that you ever come across for the rest of your life. You are empowered !
What is the formula to finding the diameter of a circle that has a circumference?
Circumference = Pi * D (the diameter) Therefore D = Circumference / Pi Naturally all circles have a circumference, but if this value is known then we can find the diameter by dividing this value by Pi. (Note: Pi is a special number and we can only ever use an approximation to its value.)
Who discovered the area of the circle?
Nobody ever has because the true value of pi has never been worked out and we only use an approximation of pi when calculating the area of a circle.
Did pi ever solve a problem?
The constant "pi" 0,314159...... is used in every branch of science, from calculating material quantity for domes in construction to calculating absorption properties of new substances in chemistry. To calculate the circumference of a circle = c = 2(pi)r The area of a circle a = (pi)r² you can also use the formula (pi)d to find the circumference Although pi has solved countless problems, no problem has ever been solved with whatever pi equals EXACTLY. Therefore, when using pi to solve a problem, the majority of mathematicians and scientists round pi down to 3.14

When was pi discovered by the Greeks?
It wasn't because even today no one has ever discovered the exact value of pi and all we know is that its value is that of a circle's circumference divided by its diameter which is an irrational number.
