The circunference of a circle equals pi times tge diameter. Using 3.14 to approximate pi, what is the approximate circunference in inches of a circle with a diameter of 1/2 in.?
The diameter of the circle is 1/2 inch.
So, the circumference of the circle is given by:
Circumference = pi * diameter
Approximating pi as 3.14, we have:
Circumference = 3.14 * (1/2) inch
Circumference = 1.57 inches
Therefore, the approximate circumference of a circle with a diameter of 1/2 inch is 1.57 inches.
To find the approximate circumference of a circle with a diameter of 1/2 inch using the approximation of pi as 3.14, you can apply the formula:
Circumference = π × diameter
Let's substitute the given values:
Circumference = 3.14 × (1/2)
To simplify, we can multiply 3.14 by 1/2:
Circumference = 3.14 × 1/2 = 3.14/2
Dividing, we find:
Circumference ≈ 1.57 inches
Therefore, the approximate circumference of a circle with a diameter of 1/2 inch is 1.57 inches.
