15. What is the radius of a circle that has a circumference of 3.14 meters?
Solution:
Circumference of a circle = 2πr.
Given, circumference = 3.14 meters.
Therefore,
2πr = Circumference of a circle
2πr = 3.14.
2 × 3.14r = 3.14,[Putting the value of pi (π) = 3.14].
6.28r = 3.14.
r = 3.14/6.28.
, r = 0.5.
Answer: 0.5 meters.
