The area of a circular field is 154msqu. What is the perimeter of the field?(pi=22/7) 44 49 88 176
OLga [1]

Answer:

44m

Step-by-step explanation:

A = \pir² = 154

   = 22/7 * r² = 154

   = r²  = 154 * 7/22

                               = 44/7 * 7

                               = <u>44 m</u>
