Answer»

2πr=2*22/7*7=44 cm is right answer

area of circle=154let radius be r22/7r^2=154r^2=154*7/22= 7*7r=√7*7=7perimeter (circumference)=2*22/7*7=44cm

πr²=154 22/7r²=154r=7cmperimeter=2πr=44

option C is a correct answer

answer is c option correctly

option (c) 44cm is the correct answer ....bcuz 2rootr =2×22/7×7=44
