408 views
To estimate diameter, measure the circumference of the circle and divide it by π (pi, approximately 3.14159). Alternatively, if you have access to calipers, position them across the widest part of the circle to directly measure the diameter. This straightforward technique ensures accurate estimation in practical contexts.
