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

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

the discriminant is 64 + 4*1*12 = 112

this is prime.
