The picture represents three steups. How can these setups be used to detrmine the strength

Rashid [163]

Step-by-step explanation:

The battery of setup 'a' is the strongest, this is indicated by the glowing of the bulb, as we can see the bulb is the brightest at the setup 'a'. Next moving on to the setup 'b', in this setup, the bulb is glowing a bit dimmer than the setup 'a', hence we can find out that setup 'b' battery strength is a little less than 'a'. Now coming to setup 'c', here we see that the bulb is not even glowing which indicates that the battery has no strength or that it has been used up.

Answer:

Second option is correct

$Arc\ length = \frac{3}{4} \pi\ in$

Step-by-step explanation:

Given:

Central angle = 15°

Radius of the circle = 9 in

Arc length = ?

Given formula is

$\frac{Arc\ length}{Circumfrance} = \frac{n}{360}$

Where n is the central angle of the sector.

Write the given formula for Arc length of the sector.

$Arc\ length = Circumfrance\times \frac{n}{360}$

We know that the the circumference of the circle is $2\pi r$ , where r is the radius of the circle,

$Arc\ length = 2\pi r\times \frac{n}{360}$

Now we substitute central angle value and radius value in above equation.

$Arc\ length = 2\pi 9\times \frac{15}{360}$

$Arc\ length = 18\times \pi \frac{15}{360}$

$Arc\ length = \frac{18\times 15}{360} \pi$ ----------( $\frac{18}{360}=\frac{1}{20}$ )

$Arc\ length = \frac{15}{20} \pi$

Divide the numerator and denominator by 5.

$Arc\ length = \frac{3}{4} \pi\ in$

Therefore the arc length of the sector is $\frac{3}{4} \pi\ in$
