Expert Answer:

Radius ratio can be calculated-
r subscript blank subscript circled plus end subscript over r subscript minus equals 122 over 125 equals 0.976

r a d i u s space r a t i o space equals 0.976

2 left parenthesis r subscript blank subscript circled plus end subscript r subscript minus right parenthesis equals square root of 3 space a
2 left parenthesis 122 plus 125 right parenthesis equals square root of 3 space a
a equals 285.2 space p m
