a ferris wheel rotates 9pi/8 radians prior to making a stop the total height of the ferris wheel is 246 ft how far around did th
Zinaida [17]

Answer:

ferris wheel travel approx = 434.72 ft

Step-by-step explanation:

given data

wheel rotates = 9pi/8 radians

total height of the ferris wheel =  246 ft

solution

we can say here that height of the ferris wheel is same as the diameter of the wheel

and wheel is circular in shape

so we get here first radius of wheel that is

radius = half of diameter    ..........................1

put here value and we get

radius = 0.5 × 246

radius = 123 ft

and

wheel travel distance = length of arc by a angle of wheel rotates

so here length of arc will be

arc length = radius × wheel rotates angle   .....................2

put here value and we get

arc length  = 123 × \frac{9\pi }{8}

arc length = 434.7178 ft

so ferris wheel travel approx = 434.72 ft

Given: triangle ABC,
Andrei [34K]

The value of AD in triangle ABC is approximately 9 cm.

BC = 6cm

Using trigonometric ratio for triangle CBD

sin 60° = opposite / hypotenuse

0.86602540378  =  DC / 6

cross multiply

DC = 6 × 0.86602540378

DC = 5.19615242271

DC = 5.20 cm

Let's find side AD as follows:

tan 60° = AD / adjacent

AD = 5.20 × tan 60°

AD = 9.00666419936

AD ≈ 9 cm
