A circle is a curve sketched out by a point moving in a plane. The diameter of the circle whose circumference is 8π cm is 8cm.
What is a circle?
A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.
The circumference of a circle is given by πD, where D is the diameter. Now, the circumference can be written as,
Circumference of the circle = πD
8π cm = πD cm
D = 8 cm
Hence, the diameter of the circle whose circumference is 8π cm is 8cm.
