Question

barry has an ice tray that makes ice cubes shaped like a cone with a diameter of 2 cm and height of 2 cm to the nearest cubic centimeter what is the volume of an ice cube from barry's tray 2cm2 8cm3 25 cm3 101 cm2

Answer 1

Answer
2 cm²

Explanation 
The volume of a cone is found by the formula;
Volume =1/3 πr² h
Where π=3.142
r=2/2=1 cm
h=2 cm
Volume = 1/3×3.142×1²×2
2.09466667
To the nearest whole number the answer is 2 cm². 

Answer 2

We know that
the volume of a cone=(1/3)*pi*r²*h
where
r is the radius
h is the height

in this problem
diameter=2 cm
so
r=diameter/2-----> r=2/2-----> r=1 cm
h=2 cm
volume of a cone=(1/3)*pi*1²*2------> 2.09 cm³------> 2 cm³

the answer is
2 cm³
