The area of this circle is 42 π m2. what is the area of a 60° sector of this circle.

this is just to people : )

The Area of sector is 7 m²

Step-by-step explanation:

Given as , for a circle :

The Area of circle = 42 m²

The angle of sector = Ф = 60°

∵ Area of circle =   × r²     , where r is the radius of circle

or, 42 m²  = × r²  

∴ r²  = 42

Now,

Area of sector =   × r² ×

Or, Area of sector =   × 42 ×

or, Area of sector =   × 42 ×

∴ Area of sector =   × 7

I.e Area of sector = 7 m²

Hence The Area of sector is 7 m²  . Answer

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
