They came because of Rinderpest. Before coming to South America, Africans in Africa depended on cattle such as cows to thrive. But Rinderpest brought to Africa by foriegners began to spread, and the cattle started to suffered from fevers, inflammation in the brain and dysentery. They also had major problems with Europeans and their industries. So they decided to settle in South America.
Hope this helps :)

<span>Using the formula 1/2*b*h for the area of a triangle, we get 7.8 cm^2 as the area of the base. Now let us assume that the three faces of the pyramid are of the same dimensions. So by subtracting 7.8 from the total surface area and dividing by 3, we get a face area of 29.6 cm^2. We get a height of 19.73 cm (using a "base" of 3 cm). Using half of the face of the pyramid (a right triangle) and applying some trigonometry (19.73 cm/sin 60) we get 22.78 cm as the slant height of the pyramid.</span>
