    There's a question that says "The cross section of the barrier is shown below .It is made from a circular tube of radius 20cm with a flat base .Calculate the volume of rubber needed for a 10 m length of tubing "can anyone solve this and tell me how to do this as I'm very confused ,thanks!

    I will asumr that this is a cylinder, with a circel at the front with a length of 10m. Difficult without the diagram.

    Area of circle is pi * radius squared = 3.14 * (0.2m)^2 = 0.1256 square metres

    Volume therefore is 0.1256 m^2 * 10m = 1.256 cubic metres.
