Answer:
Cylinder = D.) V = π · r2 · h
Cone = I`m not sure for this one.
The equation is supposed to be: V = (1/3) · π · r^2 · h
(Possibly C?)
Sphere: I`m not sure for this one.
The equation is supposed to be: V = (4/3) · π · r^3
(Possibly F?)
Sorry if that wasn`t much help but the options provided are weird...
