Pls pls pls helpp I will give u brainlyiest

Answer 1

Answer:

Step-by-step explanation:

The circumference formula is

$2\pi r$

where r is the radius

The circumference of the NAVY Pier Wheel is 439.6

We know the circumference so we solve for r.

$2\pi r=439.6$

$r=69.6=70$

So our radius is 70.

The circumference of Navy is 56% of the original wheel. So we can just set up a proportion.

$\frac{56}{100} =\frac{439.6}{y}$ to find the new circumference.

We simplify that and we get y=485

Know we find the radius,

$2\pi r=785$

r=$\frac{785}{2\pi } =125$

So our radius is 125.

3. The  first Ferris wheel circumference is 785. We divide 9 by that to find the wheel  movement per minute.

785/9= 87.2 feet per minute
