Answer:
Step-by-step explanation:
The circumference of a circle is also the perimeter of the circle. The formula for determining the perimeter of a circle is expressed as
Perimeter = 2πr
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Therefore,
Circumference = 2 × 3.14 × 4 =
25.1 feet rounded to the nearest 0.1
The formula for determining the area of a circle is expressed as
Area = πr²
Area = 3.14 × 4² = 50.2 square feet rounded to the nearest 0.1
