find the circumference and area of a circle with a diameter of 16 feet
Area = (pi/4) D^2
Circumference = pi * D
pi = 3.142
You do the numbers.
To find the circumference and area of a circle, you can use the formulas:
Circumference = π * diameter
Area = (π/4) * diameter^2
Let's calculate:
Given that the diameter is 16 feet, we can substitute this value into the formulas.
Circumference = π * 16
Area = (π/4) * 16^2
Now we need the value of π (pi). π is a mathematical constant approximately equal to 3.14159. We can use this value to compute the circumference and area.
Circumference = 3.14159 * 16
Area = (3.14159/4) * 16^2
Finally, we can simplify and calculate the values:
Circumference ≈ 50.26548 feet
Area ≈ 201.06193 square feet
So, the circumference of the circle is approximately 50.26548 feet, and its area is approximately 201.06193 square feet.
