Answer:
volume of the cylinder = 1583.36
Step-by-step explanation:
where volume of a cylinder = π h
where h = 14 ft
diameter 12 ft, so radius = 12 / 2 = 6 ft
therefore volume = π * * 14 = 1583.362697 to the nearest tenths place will be 1583.36
Given :
Emily sells erasers for $2 per package and pencils for $5 per package. she sells 220 total packages and earns $695.
To Find :
The number of packages of erasers and pencils that were sold .
Solution :
Let, number of erasers are x and pencils are y.
So, x + y = 220 ....1
Also, 2x + 5y = 695 ....2
Solving equation 1 and 2, we get :
x = 220 - 85 = 135
Therefore, the number of packages of erasers and pencils that were sold are 135 and 85 respectively.
Hence, this is the required solution.
