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 $=\pi d$

Therefore, Circumference of the Unicycle's wheel $=12\pi$ inches

Since the distance traveled in one revolution= $12\pi$ inches

Distance traveled in 6 revolutions=6 X $12\pi$ inches

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

Answer from: melindapeckens

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 = $\frac{D}{2}$

= $\frac{12}{2}$

= 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 = 2 $\pi$ r

Thus,

the circumference of the wheel = 2 × $\frac{22}{7}$ × 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.

step-by-step explanation:

Answer from: Quest

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
