The diagram shows a circle, with centre CCC, with equation (x+2)2+(y+1)2=25(x + 2)^2 + (y + 1)^2 = 25(x+2)2+(y+1)2=25. The circle intersects the xxx-axis at A A\,A and intersects the yyy-axis at BBB. The sector ABC ABC\,ABC is shown on the diagram.

Shown that angle ACB=0.958ACB = 0.958ACB=0.958 radians to 3 significant figures.
Find the perimeter of sector ABCABCABC.
