Find the volume of the cylindrical barrel that has a diameter of 14mm and a height of 4mm. Round your answer to the nearest tenth.

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.
