Answer 1

You need to know these formulas

Volume of a cone = \(\dfrac{1}{3} \pi r^2 h\)

Volume of cylinder = \( \pi r^2 h\)

Answer 2

Another way to write that is

volume of cone = 1/3 * area of base * height

volume of cylinder = area of base * height

the area of the base is 15
the height is 3

can you calculate the volume now?
