Question

The cross-section of a pipe has a width of 6 centimeters and a height of 15 centimeters.

Calculate the volume of the pipe.

Use 3.14 for pi. Round to the nearest tenth.

Answer 1

Volume of the pipe = 423.9cm³

Explanation:

Width = 6cm = diameter

Radius (r) = d / 2 = 6 / 2 = 3cm

Height = 15cm

Volume = ?

π = 3.14

Assuming the shape of the pipe is that of a cylinder, then we can easily find its volume just by calculating the volume of the cylinder.

Volume of a cylinder = πr²h

π = 3.14

r = radius of the cylinder

h = height of the cylinder

Volume = 3.14 × 3² × 15

Volume = 3.14 × 9 × 15

Volume = 423.9cm³

The volume of the pipe is 423.9cm³
