Question

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

this is just to help people :)

Answer 1

Answer:

The Area of sector is 7 $\pi$ m²

Step-by-step explanation:

Given as , for a circle :

The Area of circle = 42 $\pi$ m²

The angle of sector = Ф = 60°

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

or, 42 $\pi$ m²  = $\pi$ × r²  

∴ r²  = 42

Now,

Area of sector =  $\pi$ × r² × $\frac{\Theta }{360^{\circ}}$

Or, Area of sector =  $\pi$ × 42 × $\frac{\60° }{360^{\circ}}$

or, Area of sector =  $\pi$ × 42 × $\frac{1}{6}$

∴ Area of sector =  $\pi$ × 7

I.e Area of sector = 7 $\pi$ m²

Hence The Area of sector is 7 $\pi$ m²  . Answer
