The ferris wheel has a radius of 70 feet. the distance between the wheel and the ground is 4 feet. the rectangular coordinate system shown has its origin on the ground directly below the center of the wheel. write the equation of the circular wheel. (justify)

show your work. i will give brainliest.

The equation of the circular wheel is .

Step-by-step explanation:

Given :

Radius of Ferris wheel r = 70 feet.

The distance between the wheel and the ground = 4 feet.

Also, the rectangular coordinate system shown has its origin on the ground directly below the center of the wheel.

So the x coordinate of center of wheel must  be 0 , and y coordinate = 70 + 4 = 74

Thus, Coordinates of center = (0,74)

The equation of circle is given by :-

Now center (h,k) = (0,74) and r = 70 , we get

Hence, the equation of the circular wheel is .

215.92 dollars is the answer

so, converting firstly the mixed fractions to improper fractions and then "adding".
