Step-by-step explanation:

Ответ:
top: pi*r*r=81pi
bottom: 81pi
lateral: 2pi*r*h=18pi*h, h is unknown, but you don't have to solve it.
add them up: 81pi +81pi + 18h*pi=1850
pi*h=(1850-162pi)/18, (plug this in the volume formula below.)
volume of a cylinder: the area of the base × the height =81pi*h
volume=81[1850-162pi)/18]
use your calculator: V=6036
please double check my calculation by yourself.
