If given a complex shape how do you find the true centroid?

• Break it into smaller shapes and add the centroid locations together

• Break it into smaller shapes and average the centroid locations

• Break it into large shapes and subtract the smallest from the largest

• Multiply the centroid locations with the shape area, add the products up, divide by total shape area
