Answer:
Part A) Circumference
Part B) C=π D
Part C) The distance traveled in one rotation is 628.32 feet
Step-by-step explanation:
Part A) we know that
The distance around the circle is equal to the circumference.
The Ferris Wheel have a circular shape
so
To find out the distance around the Ferris Wheel you should use the circumference
Part B) What is the formula needed to solve this problem?
we know that
The circumference is equal to multiply the number π by the diameter of the circle
so
C=π D
Part C) What is the distance traveled in one rotation?
we know that
One rotation subtends a central angle of 360 degrees
The distance traveled in one rotation is the same that the circumference of the Ferris wheel
we have
----> diameter of the Ferris wheel
substitute in the formula of circumference
assume
therefore
The distance traveled in one rotation is 628.32 feet
Answer:
Step-by-step explanation:
The inequality can be seen graphed in the number line that I have created in the attached picture below. As you can see the open circle represents the value 1 1/4 and is an open circle because it is not included in the inequality. This is because the variable z is less than but NOT equal to 1 1/4. Also since z is any number less than 1 1/4 then the number line goes towards negative infinity.
The answer is 400 degrees because 325 + 75 = 400 degrees
Answer:
it takes 18 minutes longer
Step-by-step explanation:
26 - 8 = 18
Answer:
1.797 mm
Step-by-step explanation:
The key to solving this problem is finding the length of the coin wrapper, or "height" of the cylinder.
The volume of a cylinder equation is:
V = hπr^2
- We want to find h
- We are given diameter and we will want the radius so we divide
21.17/2 = 10.585
r = 10.585
So to find h we manipulate the equation by dividing both sides by pi and r^2
resulting in the following:
h =
now substitute given values and we get
h = = 80.883
Now to find the thickness of a single coin we divide the length of the sleeve (h) by the number of coins in the sleeve (45).
Thickness = 80.883/45 = 1.797 mm
