Answer:
a)[tex]40\pi ft^3[/tex]
b)125.68ft³
Step-by-step explanation:
The formula for volume of a cylinder is
[tex]V=\pi *r^2*h[/tex]
Given in the question
Diameter=4ft and height =10ft
You know radius is half the diameter,
radius, r=4/2= 2ft
Finding the volume in terms of pi
[tex]V=\pi *r^2*h\\\\V=\pi *2*2*10\\\\\\V=40\pi ft^3[/tex]
Substitute pi with its value,
pi=3.142
Find volume
[tex]V=\pi *r^2*h\\\\\\V=3.142*2*2*10\\\\V=125.68ft^3[/tex]
