Answer:
V = 150.72 cm³.
Step-by-step explanation:
First, get the volume of a cylinder.
V = πr²h
Where:
π = 3.14 (given)
r = radius (half of diameter, or 2)
h = height (12)
Knowing this, substitute the known values.
V = πr²h
V = (3.14)(2²)(12)
Square 2.
V = (3.14)(4)(12)
Multiply 3.14 and 4.
V = (12.56)(12)
Multiply 12.56 and 12.
V = 150.72.
Since it is already rounded to the nearest hundredth, that is your answer.
Mr. and Mrs. Lorenzo have saved $38,430 for the home they want to buy
Information about the problem:
- Initial cost = $213,500
- Savings = 18%.
- Final savings =?
To solve this exercise we have to apply the percentage formula:
Final savings = initial cost * savings / 100
Final savings = $213,500 * 18 / 100
Final savings = $213,500 * 0.18
Final savings = $38,430
