Answer: (4) 13.3 cm
Explanation:-
According to the question,
In the figure-

RE: What will the Distance Between Their Centers? If


Distance of OP = (102 – 62)1/2
= (100 – 36)1/2
= (64)1/2
= 8 cm
Distance of OP = (82 – 62)1/2
= (64 – 36)1/2
= (28)1/2
= 5.3 cm
The distance between their centers = 8 + 5.3 = 13.3 cm.
Hence, the answer is (4) 13.3 cm.
