Complete Question
Find the circumference of the pizza to the nearest hundredth.
When Diameter = 18 in.
Answer:
56.55 inches
Step-by-step explanation:
A pizza is circular in shape.
The formula for the circumference of a circle is given as:
πD
Where D = Diameter
From the above question,
Diameter = 18 inches
Hence,
Circumference of the circular pizza = π × 18 inches
= 56.548667765 inches
Approximately = 56.55 inches
The area of a circle is pi*r^2.
The angles in a circle add up to 360 degrees.
Let's say I have a circle with radius 2.
The total area of the circle is pi* (2^2) = 4pi
Let's say I cut out 15 degrees of this circle. This piece is 15 out of 360 of the whole circle.
The area of this part is (15/360) * 4pi
The rest of the area is (360-15)/360 * 4pi.
I hope this helps.
Answer:
10 feet
Step-by-step explanation:
Since the bird is 8 feet above and the badger is 2 feet below, you want to add the two lengths to get 10 feet between them.
Answer:

Step-by-step explanation:
The new pressure will be 8 kPa.
Explanation
Lets assume, the pressure of the gas is P and volume is V.
P is inversely proportional to V means :
, where
is a proportional constant.
First, it is given that, Volume of hydrogen is 3.67 liter with a Pressure of 4 kPa
Now plugging V= 3.67 and P= 4 in the above equation:

Now, we are moving all of the hydrogen to a 1.835 liter container. That means now the Volume is 1.835 liter
Plugging V= 1.835 and k= 14.68 into the original equation
,

So, the new pressure will be 8 kPa.
