A steel tube has an outside diameter of 15 cm, an inside diameter of 13 cm,and is 3.7 m long.
What is the volume of the steel contained in the tube in cubic cm is?

  • math -

    Use volume for cylinder : V = pi * r^2 * h

    Find the volume of the 15cm tube
    Find the volume of the 13cm tube
    Subtract
    Use 3.14 or 22/7 for pi

    a steel tube has an outside diameter of 15 cm, an inside diameter of 13 cm, and is 3.7 m long. The volume of the steel contained in the tube in cubic cm is ?

    V= pi*r^2*h
    V= pi*7.5cm^2*370cm
    V= pi*56.25cm*370cm
    V= 65384.397

    V= pi*r^2*h
    V= pi*6.5cm^2*370cm
    V= pi*42.25cm*370cm
    V= 49110.947

    65384.397- 49110.947 = 16273.45
    V= 16273.45
