Question

part b determine the minimum and maximum circumference, in millimeters, of the regulation discus minimum 688 maximum 694 mm mm

Explanation:

Step1: Recall circumference formula

$C = 2\pi r=\pi d$ (where $C$ is circumference and $d$ is diameter)

Step2: Calculate minimum circumference

Using minimum diameter $d = 688$ mm, $C_{min}=\pi\times688 = 688\pi$ mm

Step3: Calculate maximum circumference

Using maximum diameter $d = 694$ mm, $C_{max}=\pi\times694 = 694\pi$ mm

Answer:

Minimum circumference: $688\pi$ mm, Maximum circumference: $694\pi$ mm
