Question

If the circumference of a circle is 31.4 what is the radius....Use 3.14 for pi

Answer 1

❤️Heya buddy !! ❤️

Your answer ...

Circumference of the circle = 2πr

31.4 = 2 x 3.14 x r

10 = 2 x r

r = 5

hope helps !! ❤️❤️

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.
