Answer: 14 m
Step-by-syep Solution:
Area of circle = πr²
Substitute the given values into the formula:
153.86 = πr²
153.86 m² = (3.14)(r)²
Divide 3.14 to both sides to isolate r²:
49 m² = r²
Find the square root of both sides to cancel ²:
7 m = r
Now that we have the radius, we can apply this to the formula for the diameter of a circle:
Diameter of a circle = 2r
Substitute:
d = 2r
d = 2(7 m)
d = 14 m
