Question

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

Answer 1

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.

hope it helps you

Answer 2

Answer:

the radius of the circle is 1/2 m .

Explanation:

circumference of a circle = 2\pi R( radius).

using the formula :

and substituting the value

3.14= 2*3.14 * R

3.14/2*3.14= R

1/2=R

R= 1/2 m
