The square root of 3 is irrational, but when multiplied by itself it becomes 3.

This also applies to other square rooted numbers, such as the square root of 5, 6,7 and so on, but not number sthat make even squares, like the square root of 4 or 9.

That should convince Erika!

Riders on a Ferris wheel travel in a circle in a vertical plane. A particular wheel has radius 20 feet and revolves at the const

Zarrin [17]

It will take a rider 10 seconds to travel from the bottom of the wheel to a point 10 vertical feet above the bottom.

The radius of the wheel is 20 feet it revolves at the constant rate of one revolution per minute

using cos function,

cos ∅ = $\frac{\frac{R}{2} }{R}$

= $\frac{10}{20}$

= $\frac{1}{2}$

∅ $=60^{0}$

we know that, 1 minute = 60 seconds = $360^{0}$

1 second= $6^{0}$

∴Time = $\frac{60}{6}$ =10 seconds

Hence, it will take a rider 10 seconds to travel from the bottom of the wheel to a point 10 vertical feet above the bottom.
