wrong this answer not match in my book
Dear, it is impossible that my answer is wrong. Sometimes books given answer is wrong...
area = pi r^2 dividing both sides by pi r^2 =area upon pi root on both sides r=root of area upon pi

area = 6.16msq
πrsq=6.16
22/7*rsq=6.16/100
22/7*rsq=616
rsq=616*7/22
rsq=4321/22
rsq=196
r=√196
r=14m
diameter=14*2=28m
radius=14m
circumfrence=2πr
=2*22/7*14
=44*2
=88m
