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.

Select all quantities that are proportional to the diagonal length of a square.

horsena [70]

Answer:

B. Perimeter of a square and

C. Side length of a square

Step-by-step explanation:

if n= side length of square then

Area of square is $n^{2}$
Perimeter of a square is 4×n
diagonal length of a square is $\sqrt{2}$ × n

Thus,

Perimeter of square can be expressed as

$2\sqrt{2}$ ×diagonal length of a square

Side length of a square can be expressed as

$\frac{1}{\sqrt{2} }$ ×diagonal length of a square

but Area of square is

$\frac{1}{\sqrt{2} }$ ×n×diagonal length of a square

As a Result, Area of square is <em>also dependent of the value n</em>, wheras in other cases it is <em>a proportion of diagonal length of a square</em>
