Question

What is the radius of a circle that has a circumference of 104 ft

Answer 1

Answer:

Radius of the circle = $16.56 \,feet$

Step-by-step explanation:

Circumference of a circle= $2\times \pi \times r$

As,

          $\pi =\frac{22}{7} =3.14$

For, $Circumference=104\,feet$

             $104=2\times 3.14\times r\\\\104=6.28\times r\\\\r=\dfrac{104}{6.28} \\\\r=16.56\,feet$

The Radius of the circle is : $16.56 \,feet$

Answer 2

Answer: r = 16.55 ft

Step-by-step explanation: C=2πr

                                             r=C/2π = 104/2 x π ≈ 16.55211ft
