Consider a prism with a height of 8 inches and a 14-inch by 14-inch square base, and a cylinder with a height of 10 inches and a
vekshin1

Answer:

782.5inch³

Step-by-step explanation:

<u>The question is on volume of a prism and that of a cylinder</u>

<u>Finding the volume of the prism</u>

V=Bh where B is the base area and h is the height

Base area=14"×14"=196 inch²

height =8"

v=196×8= 1568 in³

<u>Finding volume of the cylinder</u>

v=\pir²h where r is the radius of cylinder and h is the height of cylinder

r=10/2=5 inches and h=10 inches

v=3.142×5×5×10=785.5inch³

<u>The difference in volume</u>

Difference in volume=1568-785.5=782.5inch³

Ms. Gallegos works 8 hours per day. She made $2,400 for working 10 days. How much money does Ms. Gallegos make per hour?
Zielflug [23.3K]
First, calculate the number of working hours in 10 days:

8 hours × 10 days = 80 hours

We can now rephrase the original statement to say "Ms. Gallegos made $2,400 for working 80 hours." Use this information to create the following equation:

80w = 2,400

Divide both sides by 80:

w = 30

Ms. Gallegos' hourly wage is $30

I hope this helps!
