Answer:
857.766cm^3
Step-by-step explanation:
Given data
Lenght = 3m
Internal radius r = 3m
External radius R= 10m
Volume of pipe= πr^2h
Volume of metal= External - Internal
Volume= πR^2h-πr^2h
Volume= πh(R^2-r^2)
Volume= 3.142*3(10^2-3^2)
Volume= 3.142*3(100-9)
Volume= 9.426*(91)
Volume= 857.766cm^3
Hence the volume of the metal is 857.766cm^3
Answer:
x,y=-5,-6
Step-by-step explanation:
Given
Erin Lytle's gross pay is $26,300
She takes a married exemption of $4,000
state income tax rate is 5.5%
Find out she pay in state income tax
To proof
Gross pay = $26,300
married exemption = $4,000
Let the she pay in state income tax = x
5.5 % written in the simpler form
= 
= 0 .055
than the equation becomes
x = 0.055 ( 26300 - 4000)
x = 0.055× 22300
x = $1226.5
Erin Lytle pay in state income tax is $ 1226.5
Hence proved
