Answer:
Exact Circumference = 3π feet
Approximate Circumference = 9.42 feet
Exact Area = 2.25 π ft²
Approximate Area = 7.07 ft²
Step-by-step explanation:
Diameter = d = 3 feet
Radius = r = 1.5 feet
<u><em>Circumference:</em></u>
Outline of the pit is the circumference.
=> Circumference =
Where d = 3 feet
=> <u>Exact Circumference = 3π feet</u>
=> <u>Approximate Circumference = 9.42 feet</u>
<u><em>Area:</em></u>
Area of Circle = πr²
Area = π(1.5)²
<u>Exact Area = 2.25 π ft²</u>
<u>Approximate Area = 7.07 ft²</u>
