The circumference of the circle = 2pi.r
Where r is the radius of the circle r=d/2
Circumference =2*pi*d/2
=2*3.14* (16/2) replacing value of pi and d
=50.24
Therefore the correct answer is 50.24

Answer: 50.27 in.

Explanation: The circumference of a circle is given by the formula 2π ⋅ r where r is the radius. The circumference is therefore
π ⋅ d where d is the diameter (d = 2r ) If d = 16 circumference is 16 π ≈ 50.27
