the circumference of a circle related to the radius as 2*r*pi and of course twice the radius is the diameter.
C = 2*pi*r
47 = D*pi
47/pi = D
D = 14.960564650638161562275073757016 inches
D ~= 15 inches

Using C = 2 pi r
By algebraic manipulation
r = C/2 pi
d = C/pi
d = 47/3.14 = 14.96 ins.
to the nearest inch = 15 inches.

Circumference = 47 inches
C = (pi)D
D = C/pi = 47/pi

1 full rotation is its circumference
C=(pi)d, d=C/(pi)
d=47/3.14 =14.97 in.
To the nearest inch is 15 in.

P= (3.14) x d
===========> 47=3.14d ====> d = 14.96

s=(pai)j
47=(pai)j
47/(pai)=j
2(47/(pai))=d
