Given, C= 2.5m

Circumferemce of circle = 2πr or πd

= 22/7 × 25/10

= 7.85m(approx)

Step-by-step explanation:

Circumference is 2πr.

The radius (r) is half of the diameter, but multiplying r by 2 is the same as just using the diameter in this formula, so:

2.5π

When you multiply you get 7.85 to the nearest hundredth.
