Circumference is the perimeter of a circle.
The perimeter of a circle is its circumference.
it means make same shapes only perimeter
send signals
Like condoms.
No. For example, a 4x1 rectangle will have an area of 4 and a perimeter of 10. A 2x2 rectangle will have the same area of 4, but a perimeter of 8.
Any plane shape can have the same perimeter as any other plane shape.
The perimeter of a circle is the same as its circumference
yes, it's the same as perimeter just for a circle.
