Calculate the length of the circumference of a circle with diameter of 7cm? ~3
2 answers:
Length of the circumference=perimeter
Perimeter of a circle=2pir
Which is 44
The calculation for circumference is 2πr or 2 × π (pi=3.14) × radius of a circle
Since the diameter of this circle is 7cm, and the radius is half of the diameter, 7 ÷ 2 = 3.5
So, 2×3.14(π)×3.5=21.98
