Question

the area of a quadrant = 154. find it's perimeter

Answer 1

44 is the answer 
 given area of circle=154
       ⇒area of circle=πr²
                             =22/7 ×7×7.
                             =154 
so radius of the circle=7cm
 perimeter of circle=2πr
                           =2 ×22/7×7
                           =44cm
⇒perimeter of the circle=44 cm.
