Calculate to volume of the following combined cylinders \({\text{(2 dp)}}\)

The diagram shows a wooden block that has had a hole drilled in it. The diameter of the hole is \({\text{2 cm}}{\rm{. }}\) Calculate the volume of this solid \({\text{(2 dp)}}\)

A concrete beam is to rest on two concrete pillars. The beam is a cuboid with sides of length \({\rm{0}}{\text{.5 m, 3 m}}\) and \({\rm{0}}{\text{.4 m}}{\rm{.}}\) The pillars have diameter \({\rm{0}}{\text{.4 m }}\) and height \({\text{2 m}}{\rm{.}}\) Calculate the total volume of concrete to make the beam and the pillars.

Calculate the volume of the given solid \({\text{ (1 dp)}}\)

A metal pipe has an inner radius of 3 units and an outer radius of 4 units. The length of the pipe is 10 units. Taking \(\pi \approx \dfrac{22}{7}\) find the volume of the pipe.
