Question

Sabrina rode on a ferris wheel at the state fair. in one rotation she traveled 778.72 ft. What is the appointment radius of the Ferris wheel? use 3.14 for n

Answer 1

The radius of ferris wheel is 124 feet

Solution:

Given that, Sabrina rode on a ferris wheel at the state fair

In one rotation she traveled 778.72 ft

To find: Radius of ferris wheel

The distance traveled in one rotation is equal to circumference of circle

Thus circumference of circle is equal to 778.72 feet

The circumference of circle is given as:

`C = 2 \pi r`

Where, "r" is the radius and
`\pi` is a constant equal to 3.14

Substituting, C = 778.72

`778.72 = 2 * 3.14 * r\\\\778.72 = 6.28r\\\\r = (778.72)/(6.28)\\\\r = 124`

Thus radius of ferris wheel is 124 feet
