Find the area of a quadrant of a circle whose circumference is 22cm.


cheers... thumbz up plz..

  • 1

circumference of the circle = 22

formula of circumfernce=2*22/7*r

to find r

22=2*22/7*r

r=3.5

area of the quadrent of a circle=1/4*22/7*3.5*3.5

=77/8=9.628(aprrox.)

Circumference of a circle=22cm
            2πr=22cm
       
         r =  22*7/2*22=3.5 cm
  Area of a quadrant of a circle=  πr^2/4
        = (3.14)*(3.5)^2/4
        =9.61625  cm^2....
 
 
hope it helps u....plz thumbs up.....
