The circle is a term that has three possibilities, including the non-intersecting point, single common point, or two common points.
The line will touch the circle in the single common point, whereas the line will cut the circle in the two common points.
The radius is the constant distance from the circle.
The diameter is the full length that passes through the circle.
The line that joins any two circle points is known as a chord.
The circle's circumference is the perimeter of the circle that evolved around the whole circle. At the time of evaluation, you will also get the term perimeter of the circle.
The area of the given circle is equal to πr2.
Put 4 in the term r of the circle.
A = π ( 4 ) (4)
= 16 π = 50.27.
