A circle
The perimeter around a circle is known as its circumference
When the shape is a circle, then the perimeter is called"circumference".The circumference IS the perimeter of a circle.
That depends on the shape of the area. You can have different shapes that have the same area, but a different 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.
It depends on what the shape is and what information you already have.
There isn't any. The circumference is just a special name for a perimeter of a round shape.
It depends on the shape of the acre. A rectangular acre will have a different circumference than a square or round one. One acre is 43,560 square feet. If it was in a square shape, each side would be 208.7 ft on each side, so the circumference would be 4 x 208.7 ft or 834.8 ft. But what if the acre were round? Then it would be 739.7 ft in circumference.
