On a coordinate grid of three cell phone towers, eachunit represents 1 mile. The graph of the range of Tower A has the equation x2+y2= 36. Tower B is 10 miles west of Tower A. Tower C is 10 miles east of Tower A.
1.Graph the ranges of the three towers. (All three have the same range.)
2.Write the equations of the ranges of Tower B and Tower C.
3.Estimate the area of the overlap between Tower A and Tower B.
4.A new tower with a range of 8 miles is being built 5 miles west and 11 miles north of Tower A. Write the equation of the range of the new tower.
