To complete the table using the given measurements and an approximate value for π, we can use the formula for the circumference of a circle, which is C = πd, where C represents the circumference and d represents the diameter of the circle.
1. Hula hoop:
Given diameter = 35 inches
To find the circumference, we use the formula: C = πd
C = π * 35
Using an approximate value for π, let's use 3.14:
C ≈ 3.14 * 35 ≈ 109.9 inches (rounded to the nearest tenth)
2. Circular pond:
Given circumference = 556 feet
To find the diameter, we rearrange the formula: d = C/π
d = 556/π
Using an approximate value for π, let's use 3.14:
d ≈ 556/3.14 ≈ 176.6 feet (rounded to the nearest tenth)
3. Magnifying Glass:
Given diameter = 5.2 centimeters
To find the circumference, we use the formula: C = πd
C = π * 5.2
Using an approximate value for π, let's use 3.14:
C ≈ 3.14 * 5.2 ≈ 16.3 centimeters (rounded to the nearest tenth)
4. Car tire:
Given circumference = 71.6 inches
To find the diameter, we rearrange the formula: d = C/π
d = 71.6/π
Using an approximate value for π, let's use 3.14:
d ≈ 71.6/3.14 ≈ 22.8 inches (rounded to the nearest tenth)
So, completing the table using the given measurements and an approximate value for π, we have:
Hula hoop: Circumference ≈ 109.9 inches
Circular pond: Diameter ≈ 176.6 feet
Magnifying Glass: Circumference ≈ 16.3 centimeters
Car tire: Diameter ≈ 22.8 inches
