Find the diameter of a circle with a circumference of 50 mm. Round your answer to the nearest tenth.
C = Circumference
d = diameter
C = d pi Divide both sides by pi
C / pi = d
d = 50 / 3.1416 = 15.915457 m
d = 15.9 m rounded to the nearest tenth
To find the diameter of a circle with a given circumference, you can use the formula:
Circumference = π * Diameter
In this case, the given circumference is 50 mm. Rearranging the formula, we have:
Diameter = Circumference / π
Substituting the value, we get:
Diameter = 50 mm / π
To round the answer to the nearest tenth, we need to divide the circumference by π and then round the result to one decimal place.
Using the approximation of π as 3.14, we can calculate:
Diameter = 50 mm / 3.14
Diameter ≈ 15.92 mm
Rounding this to the nearest tenth, we get:
Diameter ≈ 15.9 mm
Therefore, the diameter of the circle, rounded to the nearest tenth, is 15.9 mm.
