12. Find the diameter of a circle to the nearest tenth when the circumference is 83 m.
26.4 m
130.4 m
52.8 m
260.8 m
C = 2πr
Diameter = 2r
To find the diameter of a circle when given the circumference, you can use the formula:
Circumference = π × diameter
In this case, the circumference is given as 83 m. Using the formula, we can rearrange it to solve for the diameter:
diameter = Circumference / π
Now let's plug in the given values:
diameter = 83 m / 3.14
diameter ≈ 26.4 m
Therefore, the diameter of the circle to the nearest tenth is 26.4 m.
