Answer:
The formula of finding circumference of circle is 2πr
π This specific symbol has the value of 22 / 7.
r denotes radius of the circle.
Therefore the answer is 2×22/7×3.5
= 7 you can calculate.
Understanding the formula π= Circumference/ diameter.
we know diameter=2r
Therefore,
Circumference/2r×r×2= Circumference.
So, this is the formula
