Answer:

Area of the sector = 57.26295cm²

Step-by-step explanation:

Radius of the circle=9cm

π= 3.142

Angle at B= 81° ( opposite angle of a quadrilateral)

Area of the sector = πr² * 81/360

Area of the sector = 3.142 * 9*9 * 0.225

Area of the sector= 3.142*81*0.225

Area of the sector = 57.26295cm²

Is my answer correct?
kotykmax [81]

Answer:

The short answer is: yes, the answer to "How do you do?" is "How do you do?" It is also acceptable to reply "I'm fine, and you?" and similar variations. However -- and this is important to the etiquette side of things and not so much the language side -- "how do you do?" is actually not a question!

Which list correctly orders A, B, and C from least to greatest when A = StartAbsoluteValue 7 EndAbsoluteValue, B = –6, and C = S
7nadin3 [17]
<h3>Answer:  B, C, A</h3>

Work Shown:

A = |7| = 7

B = -6

C = |-5| = 5

--------

So, A = 7, B = -6 and C = 5 which arranges to B = -6, C = 5, A = 7.

In other words, the order from least to greatest is B, C, A

I’m confused on this one
White raven [17]

All of the angles add up to 360 degrees.

180(4-2) = 360


9x+1+5x-12+8x+61

Add up all the like terms

22x+50= 360

x=14.1


We are going to add up all of the angles together and subtract them by 360 in order to find the measurement of the missing angle.

Angle C: 9(14.1) + 1 = 127.9

Angle D: 5(14.1) - 12 = 58.5

Angle A: 8(14.1) + 61 = 173.8


All of these angles add up to 360


This means that angle D is 0 degrees since all of the other angles already add up to 360.


<u>Answer</u>

0 degrees

A granite monument has a volume of 25,365.4 cm3. The density of granite is 2.7 g/cm3. Use this information to calculate the mass
Sladkaya [172]
Let units cancel out just like numbers...

25365.4cm^3(2.7g/cm^3)=68486.58g  which is 68486.6g (to nearest tenth)
