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)
Answer:
i think its the first one
Step-by-step explanation:
SORRY if you get it wrong
The complete square will be 
= 3
Step-by-step explanation:
Given,
or, 
[ by eliminating 2 from both the sides]
To make it square
or, 
[ 
or, = 9-6
or, = 3
Hence the correct option is B
