Answer:
Area of pupil = 0.007855 square inch.
Step-by-step explanation:
Given the following data;
Diameter = 0.1 inch
To find the area of the pupil (circle);
Area of circle = π(D/2)²
Area of pupil = 3.142*(0.1/2)²
Area of pupil = 3.142*(0.05)²
Area of pupil = 3.142*0.0025
Area of pupil = 0.007855 square inch.

Answer:
45°
Step-by-step explanation:
The base angles in any isosceles triangle are congruent.
? = 45°
__
The acute angles in any right triangle are complementary.
? = 90° -45° = 45°
__
However you decide to think about it, you get ? = 45°.
Assuming this is for a triangle, <z is 122 degrees
Y is the variable in the equation.
