答案:B
解析:
Choice B is correct.
The volume of a right circular cylinder of radius r and height h is V=πr^2h.
To satisfy the conditions, V≤5200 must be true:
πr^2(65)≤5200
r≤25.4647
If r≤5 centimeters, the volume will not exceed 5200cm^3.
The largest listed radius that satisfies the volume constraint is 5cm.
