The town council is building a new circular water fountain in the middle of a square park.

1. What is the mathematical name for the distance around the outside of the circle?

Radius Diameter Circumference Circular ring

2. If you draw a straight line from one side of the fountain to the other, passing exactly through the center, what is this line called?

Circular Ring Circumference Radius Diameter

3. What is the relationship between the radius and the diameter of a circle?

r=d [math]d=2r[/math] [math]r=2d[/math]

4. If the radius of the fountain is 3 meters, calculate the area of the circle.

[math]\simeq28,27m^2[/math] [math]\simeq9,42m^2[/math]9,42m [math]\simeq18,85m^2[/math]

5. If the height of the fountain is 60 cm, calculate the volume of water inside the fountain.

[math]\simeq20m^3[/math] [math]\simeq17m^3[/math] [math]\simeq11m^3[/math]

6. Draw the fountain.
