The problem tells you that C = 56.52 inches and.
Substituting these two values
into the equation for the circumference results in:
. c=2πr
56.52=2(3.14)r
56.52=6.28(r)
r=56.52/6.28
r= 9 inches
The radius of the circle is 9 inches.
therefore the diameter will be =2r = 2(9) = 18 inches

Answer:
18 inches.
Step-by-step explanation:
circumference = π x diameter
circumference =56.52 inches
let π be 22/7
hence ,
56.52 = 22/7 x d
d = 56.52 x 7 / 22
d= 17.98 inches
i.e. approximately 18 inches.
