Answer:

Diameter is 15 unit , radius is 7.5 units and circumference is [tex]15\pi[/tex] units.

Step-by-step explanation:

Given a circle with diameter = 15 units.

We need to identity the length of the radius, diameter, and circumference of the given circle.

Radius of circle is a line segment that is drawn from center to the perimeter of the circle.

Radius is half of diameter.

Thus, Radius = [tex]\frac{1}{2}\cdot 15=7.5[/tex]

Thus, radius of given circle is 7.5 units.

Circumference is the length of the boundary or perimeter.

Circumference of circle =[tex]2\pi r[/tex]

Substitute the values,

Circumference of circle =[tex]2\pi (7.5)=15\pi[/tex]

Thus, circumference of given circle is [tex]15\pi[/tex] units

Thus, diameter is 15 unit , radius is 7.5 units and circumference is [tex]15\pi[/tex] units
