Given,
The diameter of the circle = 2.8 cm
To find,
The circumference of the circle
Solution,
The diameter of the circle is equal to twice the radius of the circle
I.e. Diameter of the circle = 2 × Radius of the circle
The circumference of the circle is calculated by the formula which is given below:
Circumference = 2πr
Putting the values given above in the formula:
We will get, circumference = (22/7)× 2.8 cm
The circumference = 8.8 cm
Hence, the circumference of the circle of diameter is 8.8 cm
