Centroid of a Semicircle Calculator

Centroid is defined as the centre mass of a geometric object which has uniform density. Half the circle is termed as the semicircle. Centroid of semicircle is at a distance of 4R/3π from the base of semicircle. Use this online geometric Centroid of a Semicircle Calculator to calculate the semicircle centroid with radius r. The centroid of a semicircle is different from semicircular arc since it has all of its mass concentrated at the edge.
