Answer:

area of the circleis defined as the complete surface inside the boundary and also boundary include..........

but circumference is know as only the boundary of the circle.....

Answer:

Circumference of circle: The distance around the circular region is called its circumference. The ratio of circumference of any circle to its diameter is constant. This constant is denoted by π and is read as pie.

Circumference/Diameter = Pie

i.e., c/d = π or c = πd

We know that diameter is twice the radius, i.e., d = 2r

C = π × 2r

⇒ C = 2πr

Therefore approximate value of π = 22/7 or 3.14.
