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.

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
