The area of the fovea is approximately 0.645% of the area of the retina.
To calculate the area of the fovea as a percentage of the area of the retina, we use the formula for the area of a circle: A=πr^2, where π is approximately 3.14, and r is the radius.
Given that the diameter of the fovea is 3×10^3 μm, the radius (r) is half of the diameter, so
r= 3×10^3/2 μm.
r=1.5×10^3 μm
Now, we can calculate the area of the fovea (A fovea):
A fovea =3.14×(1.5×10^3)^2
A fovea≈3.14×2.25×10^6 μm^2
A fovea≈7.065×10^6 μm^2
Now, we can express the area of the fovea as a percentage of the area of the retina (A retina):
Percentage=(A fovea/A retina)×100
Given that A retina is 1.094×10^3 mm², we convert the area of the fovea to mm²:
A fovea≈7.065×10^6 μm^2 ×(1mm^2 /10^6 μm^2 )
A fovea≈7.065mm^2
Now, calculate the percentage:
Percentage=(7.065/1.094×10^3)×100
Percentage≈0.645%
Therefore, the area of the fovea is approximately 0.645% of the area of the retina.
