Question

Find the radius of the circle whose circumference is 3.14 meter.

Answer 1

Answer:circumference=3.14m

Circumference of circle=2pir

2pir=3.14m

2×3.14×r=3.14

r=3.14/3.14×2

r=1/2 or 0.5m

Step-by-step explanation:

Answer 2

Answer:

mark me as brainliest and thank me if the answer is useful.

Step-by-step explanation:

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.
