Step-by-step explanation:
the circumference (C) of a circle is
∙
x
C
=
π
d
←
d is the diameter
here
C
=
5
⇒
π
d
=
5
divide both sides by
π

d
π
=

The diameter is
35

.
Step-by-step explanation:
The diameter of a circle is twice its radius.
We can find the radius of the circle by the equation
circumference
=
2
π
r
Now, just plug it in as

=
2
π
r

r
=

⋅
(

⋅
(

)
r
=

Since the diameter is twice the radius,
d
=

⋅

d
=
