问题 A cylindrical can of pineapple juice contains 350 cm3 of liquid. If the can iscm tall, what is its diameter?

选项

答案10 cm

解析 The equation for the volume of a cylinder is πr2h. The question is asking for diameter, so first solve for r, then double it.
350 =πr2(14/π)
r2 = 25 cm
r = 5 cm
Since the radius is 5 cm, the diameter is 10 cm.
