A cylindrical can of pineapple juice contains 350 cm
3
of liquid. If the can is
cm tall, what is its diameter?
选项
答案
10 cm
解析
The equation for the volume of a cylinder is πr
2
h. The question is asking for diameter, so first solve for r, then double it.
350 =πr
2
(14/π)
r
2
= 25 cm
r = 5 cm
Since the radius is 5 cm, the diameter is 10 cm.
