Answer:

Radius:
$r=7.5\:units$ .

Diameter:
d=15 units

Circumference:
$C=15\pi$

Explanation:

In the given diagram, the
d=15 units.

The radius of the circle is
$r=(15)/(2)=7.5\:units$ .

The circumference of the circle is given by

$C=\pi d$

We substitute
d=15 into the formula to obtain;

$C=15\pi$
