Qt A
radius is given 5.
y can be calculated with the distance of (2,y) from the origin (0,0)
Distance is 5 as it will be radius.
5 = \(\sqrt{(2^2-0)+ y^2}\)
25 = 4 + y^2
Y = \(\sqrt{21}\)
Qt A > Qt B

Quantity A is (5^2-2^2)^(1/2) => 21*(1/2)
Quantity B is 20^(1/2)
Hence A.
Quantity B is 20^(1/2)
Hence A.
