The question requires you to apply the formular for volume.
In this case, you have a cylindrical part and the hemispheric part
Volume of the hemispheric part is given by :
V=2/3 * pi *r where pi= 3.14 and r=6/2 = 3cm
Volume of the hemispheric part will be;
V=2/3 *3.14*3*3
V=2*3.14*3=18.85 cm^3
V=19 cm^3
Volume of the cylindrical part will be;
v=pi*r^2*h where h is height of the cylindrical part given as 5 cm
v=3.14*3*3*5 =141.3
v=141 cm^3
Total volume = 141 + 19 = 160 cm^3
