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.

Answer:
20
Step-by-step explanation:
6^2 = 36 (the exponent only applies to the 6, not the entire parentheses)
(76-36) = 40
(6 - 4) = 2
40 / 2 = 20
