What is the the radius of a circle that has a circumference of 3.14 meters?

The radius of a circle is 0.5.

SOLUTION:

• The circumference of a circle is given by c = 2\pir where r is the radius.

• Now if c=3.14 then you just assign it to the equation above and
• 

That is your answer, note that π does not equal to 3.14 but the fraction is 0.99949304261 (that's only 11 digits) and the circumference is 0.4997465213

Now if you want just 2 or 3 significant digits than you can say it's 0.5 (or even 0.500) So that is.

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

or, 2πr = 3.14.

or, 2 × 3.14r = 3.14,[Putting the value of pi (π) = 3.14].

or, 6.28r = 3.14.

or, r = 3.14/6.28.

or, r = 0.5.

Answer: 0.5 meter.
