A ball is thrown upward from the top of a building the function below shows the height of the ball in relation to sea level f(t)

gavmur [86]

$\bf slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ f(x_2)}}-{{ f(x_1)}}}{{{ x_2}}-{{ x_1}}}\impliedby 
\begin{array}{llll}
average\ rate\\

-------------------------------\\\\
f(t) = -16t^2 +32t+90\quad 
\begin{cases}
t_1=4\\
t_2=6
\end{cases}\implies \cfrac{f(6)-f(4)}{6-4}$

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.
