Plz me answer this i dont need an explanation

Point A {√3 /2 ,1 /3}

Point B { 1, 1}

could not be the points on the unit circle.

Step-by-step explanation:

Unit circle :

A circle having a radius of one unit is called the unit circle.

Standard equation of circle given by

x² + y² = r²

r = radius of

∴ x² + y² = 1²

∴ x² + y² = 1

∴

Points are not on the unit circle as on substituting this x and y values

in the above equation we get

Left hand side ≠ Right-hand side

∴

could not be the points on the unit circle.

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
