Explanation:
this is just a warm-up. almost everything is already there. you only need to put the numbers in.
so, what is unclear ?
please, tell me, so that I can help better.
the radius is always half of the diameter. or the diameter is twice the radius.
in our case : 12/2 = 6 cm.
the height is plainly written in the graph : 9 cm
Vcylinder = base area × height = pi×r² × height =
= 3.14 × 6² × 9 = 3.14×36×9 = 1,017.36 cm³
Vcone = 1/3 × Vcylinder = 1/3 × 1,017.36 = 339.12 cm³
