The perimeter around a circle is known as its circumference
The distance around a two dimensional shape is known as the perimeter of the shape. If the shape is circular, it may be refered to as a circumference.
It's a perfectly rounded 2 dimensional shape Its perimeter is better known as its circumference Its diameter spans its circumference cutting through its centre Its circumference divided by its diameter is the value of pi which is an irrational number
When the shape is a circle, then the perimeter is called"circumference".The circumference IS the perimeter of a circle.
A circle
That is called the perimeter; in the case of round shapes such as circles or ellipses, it is usually known as the circumference.
Circumference is only used for circles. Perimeter is for every other 2D shape.
Qrweer
The circumference of a shape measures how far around it. It is the total length of the boundary of the shape. For circles, the circumference is given by the formula C = 2πr, where r is the radius of the circle.
Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)
the perimeter or the circumference
That depends on what shape you are talking about.
The distance around a 2-dimensional shape is known as the perimeter. It is the total length of all the sides of the shape.
