Question

find the radius of the circle its if its area is 55.44 m square

Answer 1

Answer:4.2 m

Step-by-step explanation:

Area of circle = πr^2

55.44m^2= 22/7*r^2

r^2 = 55.44*7/22

r^2 = 17.64 m

r = root 17.64m

r = 4.2 m

Answer 2

Area of circle =πr²
πr²=55.44
22/7*r²=55.44
22*r²=55.44*7
22*r²=388.08
r²=388.08/22
r²=17.64
r=√17.64
r=4.2

radius of circle is 4.2m

Hope it's help you......
