Question

The circumference of a circle is 8π cm. What is the DIAMETER of the circle?

Answer 1

i used this formula
8=pi*d

Answer 2

Circumference is given as
C=(2*pi)(r)
where
r=radius (Half of diameter)
i.e.
r=d/2

so circumference becomes.

C=(2*pi)(d/2)

Answer 3

i still dont understand what the diameter would be

Answer 4

radius is the half of diameter i.e. r=d/2

and

diameter is the twice of radius i.e. d=2r
