Answer:

2/3

Step-by-step explanation:

In the game of chance, the possibility of winning it is 1/3. This is one of two outcomes, winning or losing. Since there is a 1/3 chance of winning it, there leaves only one outcome, losing it. Since 1/3 is a third of a whole, that leaves 2/3 for the other possibility, losing it. We then find that winning it has the chance of 1/3 and losing it has a 2/3 chance.

The circumference of a circle is 28π inches. What is the length of the radius of this circle?
devlian [24]

Answer:

The radius of the circle is 14 inches.

Step-by-step explanation:

How is the circumference of a circle related to its radius?

\displaystyle \text{Circumference} = \pi\times \text{Diameter} = \pi\;(2\times \text{Radius}).

In brief,

\text{Circumference} = 2\pi\times \text{Radius}.

For this question,

  • \text{Circumference} = 28\pi, and
  • \text{Radius} needs to be found.

Divide both sides of the equation by 2\pi:

\displaystyle \frac{\text{Circumference}}{2\pi} = \text{Radius}.

\displaystyle \text{Radius} = \frac{\text{Circumference}}{2\pi} = \frac{28\pi}{2\pi} = 14.

In other words, the radius of this circle is 14 inches.
