Answer:
- circle
- y-axis
- 5 units
Step-by-step explanation:
It can be helpful to actually see the graph. For 0 ≤ θ ≤ π, a circle is developed above the x-axis, symmetrical about the y-axis (θ=π/2). For π ≤ θ ≤ 2π, the same circle is traced again in the same direction (CCW), as values of r are negative for those angles.
The circle has a radius of 2.5, centered at (0, 2.5), so the diameter is 5 units. The length of the diameter is the farthest distance between any two points on a circle.
<u>Answer</u>:
The Area of the Ferris wheel is 31400 Square feet
<u>Step-by-step explanation:</u>
The AREA formula for a circle:
The Area formula for the circle is
where
r is the radius of the circle
The area of the Ferris Wheel:
The Height of the Ferris wheel = 200 foot
Here height of the Ferris wheel is the diameter
So the Diameter = 200
Then Radius = = 100 foot
Now the area of the Ferris wheel is
=>
=>
=> 31400 square feet
