The value of pi is about 3.14, and it is the same when using both the area and circumference.

How to calculate circumference?

The circumference is given by:

Circumference = π * diameter

For circle A:

25.12 = π * 8

π = 3.14

For circle B:

9.42 = π * 3

π = 3.14

The area is :

Area = π * diameter² / 4

For circle A:

50.24 = π * (8²)/4

π = 3.14

For circle B:

7.065 = π * (3²)/4

π = 3.14

The value of pi is about 3.14, and it is the same when using both the area and circumference.
