Question

Answer

25(i) If the radius of the cabinet is r, 

r² = (2.6/2)² + (r – 0.6)²

r²= 1.69 + r² – 1.2r + 0.36

r = 1.708 m 

(ii) If the longest length for the antic is u  m,

u² = 1.708² + (1.708 – 0.6)² = 2.918 + 1.228 = 4.1456

u = 2.036  

So longest length for the antic is 2.036 m.

Note: not sure if this is the right answer.
