Answer:
circumference=2πr
r=?
area is 5544cm^2
area =πr^2
5544=22/7×r^2
5544×7/22=r^2
1764=r^2
√1764=42=r
circumference=2πr
2×22/7×42

Answer:
circumference of a cricle = 2πr
= 2×22/7× 6
= 44×6/7
= 264/7
= 37.714. ans.
Step-by-step explanation:
given =
area of circle - 5544cm2
thus.
πr2 = 5544
22/7×r2 = 5544
r2 = 5544×7/22. { so. here is the value of
r2 = 504×7/2. radius is - 6 }
r2 = 252×7
r2 = 36
r = √36
r = 6
.
