Question

Use the image of the circle to identify the length of the radius, diameter, and circumference. Leave all answers in terms of π when necessary.

Answer 1

Answer:

Radius: $r=7.5\:units$.

Diameter:$d=15$ units

Circumference: $C=15\pi$

Step-by-step explanation:

In the given diagram, the $d=15$ units.

The radius of the circle is $r=\frac{15}{2}=7.5\:units$.

The circumference of the circle is given by

$C=\pi d$

We substitute $d=15$ into the formula to obtain;

$C=15\pi$
