Blanchard city's water tower is cylindrical in shape and has a height of 40 feet and a radius of 18 feet. what is the exact volume of water the tank can hold?

The formula for volume of a cylinder is:

Volume = PI x r^2 x h, where r is the radius and h is the height.

Volume = PI x 18^2 x 40

Volume = PI x 324 x 40

Volume = PI x 12,960

The exact volume would be 12,960PI cubic ft.

The decimal answer would vary depending on what value of PI is used.

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
