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.

The area of a circle is 121 what is the radius?
6.21
What is the length of a wire which is bent to form a square of area 121 cm square?
s2, the side length squared = area = 121 s = square root 121 = 11 length total = perimeter = sum of all 4 sides = 4s = 44 cm
What is the area of a circle 22 inches in diameter?
The general eq'n for a circles area is A = pi r^(2) Hence With a diamter of 22 inches . the radius(r) is half the diameter at 11 inches. Substituting A = pi 11^(2) A = 121 pi Using pi = 3.14 Hence A = 121 X 3.14 A = 379.94 sq.ins. (NOT ins^(2))
How do you factorise x squared minus 121?
( x2 - 121 ) = (x + 11) times (x - 11)
What is 3.14 times 11 squared?
3.14 x 112 = 3.14 x 121 = 379.94
