Answer:
138.3ft^3
Step-by-step explanation:
Volume for cylinders : V = pi*r^2*h
Volume for cones : V = pi*r^2*(h/3)
Since we know the radius (r) is 2 and the height is 10 and 3 for the cylinder and cone respectively, all we do is plug in.
Volume for cylinder is about 125.7ft^3
Volume for cone is about 12.6ft^3
Then just add them together for a total of 138.3ft^3
