V = B * h
volume = area of the base * height 
The base of this shape is a circle with diameter of 10 
the radius (r)  is 5 
area of circle = pi * r^2 = pi * 5^2 = 25 pi cm^2

the height is 2 meters. The answer needs to be in cm^3 
convert m to cm 
1 m = 100 cm , 2m = 200cm 

A = B * h = 25pi *200= 5000 * 3.14= 15700 cm^3
