Diameter length of the given circle = 10 feet
And diameter of a circle = 2 times radius of the circle
Therefore 10 = 2r where r is the radius of the circle
That is 2r = 10
dividing by 2, we get
r = 5
Therefore the radius of the flower circle = 5 feet
Circumference of the circle by formula
= 2(pi)r
= 2X(22/7)X5
=220/7
=31.4285..
Therefore circumference of the circle is 31.43 feet approximately
