Find the area of the blue sector. Use 3.14 for pi and round to the nearest hundredth.

Answer:

Option C $25.64\ in^{2}$

Step-by-step explanation:

we know that

The area of a circle is equal to

$A=\pi r^{2}$

we have

$r=7\ in$

substitute

$A=\pi(7)^{2}=49\pi\ in^{2}$

Remember that

$360$ degrees subtends the complete area of the circle

so

by proportion

Find the area of the blue sector for an angle of $60$ degrees

$\frac{49\pi}{360}=\frac{x}{60}\\ \\x={49\pi*60/360$

$x=25.64\ in^{2}$

I need this problem solved real quick

PIT_PIT [208]

<u>Let's take this problem step-by-step</u>:

<u>The ;unlabeled angle' adjacent to the 'outside angle of measure 78°'</u>

⇒ is on a straight line

⇒ sum of angle measure = 180 degrees

$unlabeled_.angle+78 = 180\\unlabeled_.angle = 102$

<u>Now we know:</u>

⇒ sum of all angles in a triangle ⇒ 180°

<u>Let's put that in equation form and solve:</u>

$x + 102 + 57=180\\x + 159=180\\x = 21$

<u>Answer: 21°</u>

<u></u>

Hope that helps!
