The Municipal Disaster and Risk Reduction Management Committee (MDRRMC) advised the residents living within the 15 km radius critical area to evacuate due to typhoon Tiban. on the map that is drawn on coordinate plane, the coordinates corresponding to the location on where the landfall of the typhoon is (3, 4). If each unit on the coordinate plane is equivalent to 1 km, what is the equation of the circle enclosing the critical area?

1. write the equation of the critical area to evaluate due to the typhoon
2.sketch the graph showing the location where the landfall of the typhoon occurs and the critical area for the residents to evacuate. use graphing paper.

PLEASE HEELP LOL​
