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
