Question

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

Answer 1

Answer:

Step-by-step explanation:

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

2*pi*r = 3.14

2*3.14 *r= 3.14

r =0.5
