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
I believe the answer should be 270.
You should replace the “d” in 30d with a nine because the “d” stands for how many days. The question said there are nine days so you would get this...
30x9=270 minutes in total
Volume= area of base x height
base= 3.14 x 4^2(8/2=4 for the radius)
base=50.24
base x height=50.24 x 23=1155.52, or 1156 ft3
