Chapter 11, Problem 36SGR

To determine

To find ride for 15 rotations.

Answer to Problem 36SGR

11775 ft.

Explanation of Solution

Given Information: Diameter = 250 ft.

Formula Used: Circumference of circle = $\pi d$ , $\pi =3.14$

Calculation:

Diameter = d

Now, diameter is of 250 ft.

Circumference of circle = $\pi d$

The distance travelled in 1 rotation = Circumference of circle

The distance travelled in 15 rotation = 15 x Circumference of circle

The distance travelled in 15 rotation = $15\times \pi d$

The distance travelled in 15 rotation = $15\times \pi \times 250$

The distance travelled in 15 rotation = $3750\times \pi$

Now, $\pi =3.14$

Put the value of $\pi$ to find the circumference

The distance travelled in 15 rotation = $3750\times 3.14$ ft.

Hence,

The distance travelled in 15 rotation = 11775 ft.
