Answer:
9.74418019cm=h
~ 9.7442
Step-by-step explanation:
volume of a cylinder=πr²h
radius=½of diameter
=½×140cm
=70cm
1l=1000cm³
150l=150l/1l×1000cm³
=150000cm³
150000cm³=π(70cm)²×h
150000cm³=15393.8040cm²h
150000cm³/15393.8040cm²=15393.8040cm²h/15393.8040cm²
150000cm³/15393.8040cm²=h
9.74418019cm=h
Answer:
(D) 20%
Step-by-step explanation:
The original price of the two items = $60 + $40 = $100
The discounted price of the two items = $60 + ($40 x 0.5) = $60 + $20 = $80
To find the percent discount he received off his total purchase, we need to divide the difference between the original price and the discounted price by the original price.
$100 - $80 = $20
$20 ÷ $100 = 0.2
0.2 = 20%

Answer:
The correct answer is the first one listed.
Step-by-step explanation:
First you have to determine what the equation for that circle is. The standard form of a circle is
where h and k are the coordinates of the center and the radius is squared. Using the given info, our equation will look like this:
Now we use the coordinates given and plug in 2 for x and 3 for y and do the math and see if the 2 sides are equal.
and 9 + 16 = 25, right? So that's how you can check the other coordinate pairs to verify that they DON'T work out!
