In a circle with a diameter of 25.2 ft. An arc is intercepted by a central angle of 168°. What is the arch length? Use 3.14 for

ss7ja [257]

if the circle has a diameter of 25.2, its radius is half that or 12.6.

$\bf \textit{arc's length}\\\\ s=\cfrac{\pi \theta r}{180}~~ \begin{cases} r=radius\\ \theta =angle~in\\ \qquad degrees\\ \cline{1-1} r=12.6\\ \theta =168 \end{cases}\implies s=\cfrac{\pi (168)(12.6)}{180} \\\\\\ s=11.76\pi \implies \implies \stackrel{\pi =3.14~\hfill }{s=36.9264}\implies \stackrel{\textit{rounded up}}{s=36.93}$

An engineer spends 30% of the time at home and 40% at work, 6 mi away. The remaining 30% is spent commuting between home and wor

Ad libitum [116K]

Answer:

Step-by-step explanation:

Probability is given by number of possible outcomes ÷ number of total outcomes

The time commuting between home and work is 6mi

Probability (the engineer is at least 2mi from home) means that the engineer is either 2mi from home or more than 2mi from home

Probability (the engineer is 2mi from home) = 2/6

Probability (the engineer is more than 2mi from home) = 1 - 2/6 = (6-2)/6 = 4/6

Probability (the engineer is at least 2mi from home) = 2/6 + 4/6 = 6/6 = 1
