Answer: 615.4mm cube
Step-by-step explanation:
The volume of a cylinder is given as πr^2h
where r= radius
h = height
π = 3.14
From the question, diameter is 14mm and height is 4mm.
To get the radius, we divide the diameter by 2 which will give:
= 14mm/2 = 7mm
Volume= πr^2h
= 3.14 × 7^2 × 4
= 3.14 × 49 × 4
= 615.4mm cube
The volume of the cylindrical barrel is 615.4mm cube.
