Aregion r is enclosed by the coordinate axes and the graph of y=k(x-5)^2, k> 0. when this region is revolved around the x-axis, the solid formed has a volume of 2500pi cubic units.
what is the value of k?

The question is asking to calculate the value of K if the R is enclosed be the coordinate axis and the graph of y = k(x-5)^2, and K>0. Base on that, the value of K would be K is equals to 2, I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarifications 

The answer would be -3.9> -4.5
