Answer:
The radius of the circle is 4 meters.
Thus, 2nd option is correct.
Step-by-step explanation:
Given
Area of a circle = 16π squared meters.
To determine
The radius of the circle = r = ?
Using the formula
Area of circle = πr²
substitute Area of circle = 16π and in the equation
16π = πr²
switch the sides
πr² = 16π
divide both sides by π
πr²/π = 16π / π
r² = 16
r = 4, r = -4
As radiud can not be negative, so
r = 4 meters
Therefore, the radius of the circle is 4 meters.
Thus, 2nd option is correct.
