Radius of cone= 6
radius of cylinder =6
because both base is same
volume of cone = 263.9cm2
volume of cylinder = 1584cm2
total volume of missile =1847.9

length of cylinder,h=14cm
diameter of base,d=12cm⇒radius,r=d/2=6cm
height of cone,H=7cm
Volume of the missile=volume of cone +volume of cylinder
=1/3 πr²H+πr²h
=πr²(1/3H+h)
=3.14×6×6(7/3 + 14)
=113.04(16.33)
=1845.94 cm³
