what is the diameter of a circle with a circumfrence of 47.1
C = pi * d
47.1 / 3.14 = d
? = d
Is it 7.5, 15, 0.75, or 1.5
To find the diameter of a circle, you can use the formula:
Diameter = Circumference / π
Given that the circumference of the circle is 47.1, you can substitute this value into the formula:
Diameter = 47.1 / π
To calculate the numerical value, divide 47.1 by the value of π. The value of π (pi) is approximately 3.14159.
Diameter ≈ 47.1 / 3.14159 ≈ 15
Therefore, the diameter of the circle is approximately 15 units.
To find the diameter of a circle with a given circumference:
Step 1: Recall the formula for the circumference of a circle:
Circumference = π * Diameter
Step 2: Rearrange the formula to solve for the diameter:
Diameter = Circumference / π
Step 3: Substitute the given circumference value into the formula:
Diameter = 47.1 / π
Step 4: Use an approximation for π, which is commonly 3.14:
Diameter ≈ 47.1 / 3.14
Calculating the result gives us:
Diameter ≈ 14.99
Therefore, the diameter of the circle with a circumference of 47.1 is approximately 14.99 units.
