Given cos t = 1/2 tan 0 find sin (t) and sec (t)

777dan777 [17]

Answer:

Sin(t) = $\frac{\sqrt{3} }{2} }$ and $sec(t) =2$

Step-by-step explanation:

The secant function is the reciprocal function of the cosine function. Therefore, given that $sec(t) = \frac{1}{cos(t)}$ then, if $cos(t) = \frac{1}{2}$ then $sec(t) =2$ .

On the other hand, if cos (t) = 1/2 ⇒ t = ± $\frac{\pi}{3}$

Then, the sin( $\frac{\pi}{3}$ ) = $\frac{\sqrt{3} }{2} }$

Can someone please help me with this is area of circles

vivado [14]

<h3><u>Given Information :</u></h3>

Radius of the turbine = 32 m
π = 3

<h3 /><h3><u>To calculate :</u></h3>

Area covered by blade when the turbine makes 1 revolution.

<h3><u>Calculation :</u></h3>

We know that,

$\bigstar \: \boxed{\sf {Area_{(Circle)} = \pi r^2}} \\$

$\sf \longmapsto {Area = \{3 \times (32)^2 \} \: m^2 }$

$\sf \longmapsto {Area = \{3 \times 1024 \} \: m^2 }$

$\longmapsto \sf \red {Area = 3072 \: m^2 }$

Therefore,

Correct option is <u>option 4th.</u>
