Worksheet 1

4 problems
  1. A circular swimming pool has a diameter of 14 meters. A concrete walkway extends 2 meters outward from the edge of the pool all the way around. What is the total area of the walkway? (Use π = 3.14)
  2. Liam is designing a circular fountain for his community garden. The fountain will have a diameter of 14 feet. He needs to purchase a decorative border for the outer edge and special tiles to cover the entire surface area. How many feet of border does he need for the circumference, and what is the area in square feet that needs to be tiled?
  3. A circular garden has a radius of 9 meters. What is its circumference? Use π = 3.14.

Worksheet 2

3 problems
  1. A city is building a circular skate park with a diameter of 28 meters. The planners need to install a protective railing around the entire outer edge and calculate how much special rubber surfacing material is needed to cover the entire circular area. What is the total length of railing required (circumference) and how many square meters of surfacing material are needed (area)? Use π ≈ 3.14 and round your answers to the nearest whole number.
  2. A circular fountain has a radius of 6 meters. What is its circumference? Use C = 2πr.
  3. Liam is designing a circular fountain for his community garden. The fountain will have a diameter of 14 feet. He needs to purchase decorative tiles to cover the entire area of the fountain and a special border to go around its circumference. How many square feet of tiles does Liam need to cover the fountain's area, and how many feet of border does he need for the circumference? Use π ≈ 3.14 for your calculations.
