Find Y <br>.............. ​
N76 [4]

Answer:

y = 40 / sqrt(pi)

Step-by-step explanation:

The area is 400

We want to find the diameter

400 = pi r^2

Divide each side by pi

400/ pi = r^2

Take the square root of each side

sqrt(400/ pi) = sqrt(r^2)

20/ sqrt(pi) = r

The diameter is twice the radius

2 r = d

2 * 20/ sqrt(pi) = d

40 / sqrt(pi) =d

y is the diameter so

y = 40 / sqrt(pi)

The complete square will be  (x-3)^{2} = 3

Step-by-step explanation:

Given,

2x^{2} -12x+12=0

or, x^{2} -6x+6=0 [ by eliminating 2 from both the sides]

To make it square

x^{2} -6x+6=0

or, x^{2} -2xX3+9-9+6=0 [ (a+b)^{2}=a^{2} +2ab+b^{2}

or, (x-3)^{2} = 9-6

or, (x-3)^{2} = 3

Hence the correct option is B
