a = 154cm square
r = ?
a=πr²
154=22/7*r²
r²=154 x 7/22
r²=1078/22
r²=49
r=7 cm
c=2πr
c=2*22/7*7
c=2*22
c=44

area of a circle = πr^2
circumference of the circle = 2πr
π = 22/7
Given area = 154 cms squared
22/7 * r^2 = 154
r^2 = 154 * 7/22
r ^ 2= 49
r = 7
circumference = 2πr
2 * 22/7 * 7 = 44
and the answer is
44 cms
