Question
After stepping into a room with unusual lighting, Edmond's pupil has a diameter of 8 millimeters. What is the pupil's radius?
Solution
The radius of a circle is half of its diameter. So, to find the radius of Edmond's pupil, you would divide the diameter by 2.
Step 1: Identify the diameter. The diameter of Edmond's pupil is 8 millimeters.
Step 2: Divide the diameter by 2 to find the radius.
8 millimeters ÷ 2 = 4 millimeters
So, the radius of Edmond's pupil is 4 millimeters.
