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.

Diameter is 15 unit , radius is 7.5 units and circumference is 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 =

Thus, radius of given circle is 7.5 units.

Circumference is the length of the boundary or perimeter.

Circumference of circle =

Substitute the values,

Circumference of circle =

Thus, circumference of given circle is units

Thus, diameter is 15 unit , radius is 7.5 units and circumference is units

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base
