Answer:
Explanation:
The circumference of a circle is equal to
π
, which is a number
≈
3.14
, multiplied by the diameter of the circle.
Therefore,
C
=
π
d
.
We know that the circumference,
C
, is
16
π
, so we can say that:
16
π
=
π
d
We can divide both sides by
π
to see that
16
=
d
.
We now know that the diameter of the circle is
16
.
We also know that the diameter has twice the length of the radius.
In equation form:
2
r
=
d
2
r
=
16
r
=
8
Note that since
2
r
=
d
, the equation
C
=
2
π
r
holds and can be used in place of
C
=
π
d
.
