Answer:
V = 2458.10 cubic inches
Step-by-step explanation:
Volume of a cylinder
V = πr^2h
V - volume of the cylinder
π - pie
r - radius of the cylinder
h - height of the cylinder
Given :
π - 3.142
h - 19.1 inches
d - 12.8 inches
Calculate the radius
Diameter = 2 * radius
Radius = diameter/2
r = 12.8/2
= 6.4 inches
Find the volume
V = 3.142 * (6.4)^2 * 19.1
= 3.142 * 40.96 * 19.1
= 2458.0997 cubic inches
To nearest tenth
V = 2458.10 cubic inches
