The first circle given by the equation $(x-h_1)^2 +(y-k_1)^2 = r_1^2$ and the second circle given by $(x-h_2)^2 +(y-k_2)^2 = r_2^2$.
How to use the calculator?
1 - Enter parameters h1, k1, r1 for the first circle and parameters h2, k2 and r2 for the second circle, change the number of decimal places if necessary and press "enter".
