Given the radius of the discus used in the track field competition, the circumference of the discus is 69.08cm.
<h3>What is the circumference of the discus?</h3>
Note that; a circumference is the perimeter of a circle or ellipse.
It is expressed as C = 2πr
Where r is the radius and π is the constant pi ( π = 3.14 )
Given that;
- Radius of the discus r = 11cm
- Circumference C = ?
C = 2πr
C = 2 × 3.14 × 11cm
C = 69.08cm
Therefore, given the radius of the discus used in the track field competition, the circumference of the discus is 69.08cm.
