Answer:
use area
Step-by-step explanation:
we can't use volume here since we are dealing with the outside part only
so area of a cylinder is =πr²h
our r represents the radius which is diameter/2
r=7.5/2
=3.75m
our h represents height which is 12.5m
so put in our formula
area = π×(3.75)²×(12.5)
=552.2330836m³
that's it dear
