A right circular cylinder has a diameter of 3.7 in and a height of 7 ft. What is the volume of the cylinder in cubic feet? What is the volume in cubic meters? What is the volume in liters? During a thunderstorm, a total of 2.2 inches of rain falls. How much water falls on one acre of land? (1 mi2 = 640 acres) Express your answer in the following ways. Find the following.Explanation / Answer
1) r = d/2 = 1.85 in
1 in = 0.083 ft
a) V = pi*r^2*L = 3.14*(1.85*0.083)^2*7 = 0.518235703 ft^3
b) V = 0.518235703*(0.3048)^3 = 0.014674801 m^3
c) V = 0.014674801*1000 = 14.6748009 L
2) 1 mi = 1609 m........1m = 39.37 in...1 in = 0.0254 m..1 in = 0.083 ft
1 acre = 1/640 mi^2 = 1609^2/640 = 4045.12 m^2 = 6269933.63 in^2 = 43193.57ft^2
a)V = 6269933.63*2.2 = 13793853.986 in^3
b) V = 43193.57*2.2*0.083 = 7887.145882 ft^3
c) V = 4045.12*2.2*0.0254 = 226.0413056 m^3
d) m = 226.0413056*1000 = 226041.3056 kg
3)
a) 1.58*10^5/(60*60) = 43.88 Km/hs
b) 1.58*10^5*1000/(60*60)^2 = 12.19 m/s^2
