if the circumference of a circle is 12.56 m then what is its diameter?
C = pi * d
12.56 = 3.14d
12.56/ 3.14 = d
4 = d
I keep replying the answer for and they say that is wrong
To find the diameter of a circle given its circumference, you can use the formula:
Circumference = π * Diameter
Given that the circumference is 12.56 m, we can substitute this value into the formula:
12.56 = π * Diameter
To solve for the diameter, divide both sides of the equation by π:
Diameter = 12.56 / π
Now, calculate the diameter by dividing 12.56 by the value of π (approximately 3.14159):
Diameter ≈ 12.56 / 3.14159
Diameter ≈ 3.99 meters (rounded to two decimal places)
Therefore, the diameter of the circle is approximately 3.99 meters.
