A unicycle wheel has a diameter of 12 inches. How many inches will the unicycle travel in 6 revolutions? Round your answer to the nearest hundredth of an inch.

226.19 inches

Step-by-step explanation:

Diameter of the unicycle's wheel=12 inches

The distance traveled by the unicycle in one revolution is the circumference of the wheel.

For a circle of diameter d,

Circumference

Therefore, Circumference of the Unicycle's wheel inches

Since the distance traveled in one revolution= inches

Distance traveled in 6 revolutions=6 X inches

=226.19 inches (to the nearest hundredth of an inch.)

The unicycle would travel 226.29 inches in 6 revolutions.

Step-by-step explanation:

A unicycle wheel is a one wheeled device, unlike the bicycle which has two wheels.

The given unicycle has a diameter, D, of 12 inches. It's radius, r, can be determined by;

         r =

           =

           = 6

∴        r = 6 inches.

A revolution is a complete movement of a point forming a circle, or the movement of a point along the circumference of a circle.

Circumference of a circle = 2r

Thus,

the circumference of the wheel = 2 × × 6

                                                    = 37.7143

The circumference of the wheel is 37.7143 inches.

Therefore, for 6 revolutions the unicycle would travel:

              6 × 37.7143

             = 226.2857

The unicycle would travel 226.29 inches in 6 revolutions.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
