To calculate the diameter of a circle from its area (144 nm²), you use the area formula A = πr² to find the radius, then double the radius to find the diameter. The final diameter is approximately 13.54 nm.
The question is asking to calculate the diameter of the circle based on its given area which is 144 nm2 (nanometers squared).
In order to find the diameter of the circle, one needs to use the area formula of a circle, which is A = πr2, where A is the area and r is the radius.
First, solve for the radius using the given area:
144 nm2 = πr2
r2 = 144 nm2 / π
r ≈ √(144 nm2 / π)
r ≈ 6.77 nm
Now that we have the radius, the diameter D is simply twice the radius.
D = 2r
D = 2 × 6.77 nm
D ≈ 13.54 nm
Therefore, the diameter of the circle is approximately 13.54 nm.
