You are planning on using circles to compare the populations of California 37,691,000, Texas 25,675,000, and New York 19,465,000

kati45 [8]

The circle for New York:
r = 5 cm, Area : A = r² π = 25 π cm²
New York: 19,465,000
California: 37,691,000
Texas: 25,675,000.
-----------------------------------
California: 37,691,000 : 19,465,000 = 1.93635 N Y
1.93635 x 25 π = 48.4 π ⇒ r = 6.957 ≈ 7.0 cm
Texas : 25,675,000 : 19,465,000 = 1.319 N Y
1.319 x 25 π = 32.975 π ⇒ r = 5.742 ≈ 5.7 cm

Answer:

step 3 didn't divide by 2

Step-by-step explanation:

in step

$\frac{ - 8 + \sqrt{100} }{2} = \frac{ - 8 + 10}{2} = 1 \\ \frac{ - 8 - \sqrt{100} }{2} = \frac{ - 8 - 10}{2} = - 9$
