To find the radius of a circle with an area of 121 square units, you first need to use the formula for the area of a circle, which is A = πr^2, where A is the area and r is the radius. In this case, the area is 121, so 121 = πr^2. To solve for the radius, you divide both sides by π and then take the square root, giving you r = √(121/π) ≈ 6.18 units.
