Hello ❤️
Given area of circle is 154cm²
Area of circle =πr²
=22/7×7×7
= 154
So, Radius of circle is 7 cm
Perimeter of circle=2πr
= 2×22/7×7
= 44cm
Perimeter of circle is 44cm
Hence option (c) is correct
Hope it will help you ☺️☺️

Answer:
44 option c is right
Step-by-step explanation:
\pi*r^2=154
22/7*r^2=154
r^2=154*7/22
r= \sqrt{49}
r=7
perimeter=2*\pi*r
2*22/7*7= 44
