Question

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

Answer 1

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.

Answer 2

Answer:

1/2

Step-by-step explanation:

circumference of circle=2πR

2πR=3.14

2R=3.14/π

R=3.14/2π

R=1/2 [ bczz π=3.14 approx]
