Question

What is the area of sector AEB when AE = 8 yd?

Answer 1

We are given the radius/AE/EB as 8yd!
And we know that the angle including the sector is 90'
Thus the area of the QUADRANT is? pi*r*r/4
Just put the values in the equation and then solve it! :)

Answer 2

lol the problem is idk how to do that :p

Answer 3

What is the area of a circle? pi*r*r right?

Answer 4

yes

Answer 5

Now what is the degree of a circle = 360 right? [FROM THE CENTRE]

Answer 6

And a degree of a quadrant is 90' RIGHT?

Answer 7

right.

Answer 8

Thus the area of the sector which has 90' included should be one-fourth of the area of the circle right?

Answer 9

correct

Answer 10

Let's say the angle included was 30'
The formula would be pi * r * r * theta/360! [theta is the angle included in the sector]

Answer 11

so i should replace 120 and 30 in place of r?

Answer 12

R is the RADIUS

Answer 13

theta is the angle inbetween AE AND EB!!! :)

Answer 14

i knew that lol

Answer 15

AREA OF A SECTOR = ARE OF CIRCLE * THETA/360 [Where theta is the angle included between the 2 radii]
And in your case the angle is 90' :D

Answer 16

Just substitute and You'll get the answer!!! :)

Answer 17

Did you get it?

Answer 18

no.......... -___-

Answer 19

See you figure tells us to find the area of a sector right?

Answer 20

yes sector AEB

Answer 21

Exactly now if I gave you a PIZZA *WOHOO*
Which only has 4 slices!
Then wouldn't each slices' area be 1/4th of the entire pizza?

Answer 22

lol yea

Answer 23

i want pizza now thanks..

Answer 24

Then same in this case AEB is just like the slice and ITS area is 1/4th of the whole circle!

Answer 25

Haha... So the answer will be pi * z * z * a!!! :P
No it is pi * r * r * 1/4 :)

Answer 26

where r has a value of 8 yards!
Get it? :)

Answer 27

noo.....
jk yeah i get it (:

Answer 28

but check my answer plz

Answer 29

How much is your answer?

Answer 30

my calculator tells me that its 50.26????????

Answer 31

It should be 50.26 yd^2 then okay?
Enjoy and
Kudos the response :)

Answer 32

Good job! :)

Answer 33

its wrong though

Answer 34

its not one of my options

Answer 35

Then the question you asked me has to be wrong!

Answer 36

no its correct

Answer 37

See what the question asks!

Answer 38

What is the area of sector AEB when AE = 8 yd?

Answer 39

thats the question

Answer 40

maybe i should sqrt it?

Answer 41

Why? That is not logical AT ALL!

Answer 42

Try to get the concept!

Answer 43

i know so what should i do?

Answer 44

Is 150.28 any one of your answers?

Answer 45

these are my options.
4π yd2
16π yd2
8π yd2
2π yd2

Answer 46

And 16pi is 50.26 :PPP

Answer 47

So it is B :)

Answer 48

lol ooohhh youre right thanks!

Answer 49

Good luck buddy and TRY TO GET THE CONCEPT!

Answer 50

GOTCHAA!
