Height of a cone-shaped attic:
h = 18 ft,
d = 18 ft,
r = 18: 2 = 9 ft
V = r² π h / 3 =
= 9² π · 18 / 3 = 81 π · 6 = 486 π ft³
Answer:
The volume of the space in the attic is 486 π ft³.
The answer is C. 37

Answer:
Option D.
or 
Step-by-step explanation:
<u><em>The correct question in the attached figure</em></u>
we have
----> inequality A
subtract 5 both sides
divide by 3 both sides
The solution of the inequality A is the interval [-2,∞)
----> inequality B
adds 7 both sides
divide by -2 both sides
Remember that when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
The solution of the inequality B is the interval (-∞,-6]
therefore
The solution of the system is

Problem:
Berto has $12 to put gas in his car. If gas costs $3.75
per gallon, which ordered pair on the graph of the line relating number of
gallons of gas, x, to the total cost of the gas, y, includes the greatest
amount of gas Berto can buy?
Answer/ Solution:
<span>
Given: </span>
$ 12 – Berto’s money
$3.75- gas cost/ gallon
Asked:
Which ordered pair on the graph of the line relating
number of gallons of gas, x, to the total cost of the gas, y, includes the
greatest amount of gas Berto can buy.
(x , y)
x=?
y= 12
x= 12/ 3.75
= 3.2
X= 3.2
