88 cm
Explanation:
find r
a=22/7×r^2
r^2=616×7/22
r=sq.root 196
r=14 cm
perimeter=2 pie r
2×22/7×14^2
perimeter=88 cm
mark me as brainliest
Explanation:
Area =616cm.sq.
Area= pie r²
Circumference=2pie r
Area =3.14r²
616=3.14r²
616/3.14=r²
196.2=r²
Root196.2=r
r=14.1
Now,
Circumference=2pie×r
=>2×22/7×14.1
=88.62
