What is the diameter of a circle with a circumference of 11.27π ft?

soln,

circumference of circle = 11.27π ft

so,

C = 2πr

or, 11.27π = 2πr

or, 11.27π/2π = r

so, r = 5.635 ft

now,

diameter = 2r

= 2 x 5.635

= 11.27 ft

x

step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
