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
A
10 > 2.01
Since 2.01 has a point of decimal after the # 2, it is known is a 2 so 10 should be greater than the 2.
v=0.79x+3.99
f=1.89x+5.49
combined cost: 2.68×+9.48
