The circumference of a circle pi times the diameter. Using 3.14 to approximate pi, what is the approximate circumference in inches of a circles with a diameter of 1/2.?
To find the approximate circumference of a circle with a diameter of 1/2, we first need to calculate the radius. The radius is half the diameter, so it would be 1/2 * 1/2 = 1/4.
Next, we use the formula: circumference = π * diameter. Since we are using an approximation of π as 3.14, the circumference would be approximately 3.14 * 1/2 = 1.57 inches.
9/4 is close to the square root of what integer
To find the square root of an integer that is close to 9/4, we can try different perfect squares until we find the closest:
1^2 = 1
2^2 = 4
3^2 = 9
Based on this, we can see that 9/4 is close to the square root of 2.
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 follow these steps:
Step 1: Find the diameter of the circle:
The diameter is given as 1/2 inch.
Step 2: Calculate the circumference:
Using the formula for the circumference of a circle, which is pi times the diameter, substitute the known values:
Circumference ≈ 3.14 × (1/2) inch.
Step 3: Simplify the expression:
Multiply 3.14 by 1/2:
Circumference ≈ 3.14 × 1/2 inch.
Step 4: Perform the multiplication:
Multiply 3.14 by 1/2:
Circumference ≈ 3.14/2 inch.
Step 5: Simplify the division:
Divide 3.14 by 2:
Circumference ≈ 1.57 inch.
Therefore, the approximate circumference of a circle with a diameter of 1/2 inch, using pi as approximately 3.14, is 1.57 inches.
