)^2 = 
20) -

Answer:
V= 904.896cm^3
Step-by-step explanation:
Volume of a cylinder
V = πr^2h
V - volume of a cylinder
π - pie
r - radius of the cylinder
h - height of the cylinder
Given :
h - 18cm
d - 8cm
d = 2 * radius
r = d/2
r = 8/2
r = 4cm
π - 3.142
Insert the values into the formula of volume of a cylinder
V = πr^2h
V = 3.142 * 4^2 * 18
= 3.142 * 16 * 18
= 904.896cm^3
