i need the answer please quickly

Suppose that the data mining task is to cluster points (with (x, ) representing location) 22 into three clusters, where the points are A(2,10). A (2.5). As(8,4). B,(5,8). B, (7.5)B(6,4), (1.2). C(4.9). The distance function is Euclidean distance. Suppose initially we assign A, B, and Gas the center of each cluster, respectively. Use the k-means algorithm to solve the three cluster centers after the first round of execution. You have to write all the mathematical calculation and algorithm process
