2a) if 1 ft³ weighs 150 lb==>the TOTAL VOLUME =5,000/150 =33.334 ft³
2b) 1 ft³ 1,728 in³. So the TOTAL volume in in³ =33.334 x 1728 = 57,600 in³
c) Volume =(1/3)(πR²).H but R = H then V= (1/3)(πR³).plug V (=57600)
57,600 = 1/3 (πR³) ==> R³ = (3 x 57600) / π ==> R = 38 in
d) Area x thickness = Volume ==> Area x 2 in = 57600 in then:
Are =57600/2 & Area =28,800 in²

Answer:
3.50ft
Step-by-step explanation:
Given data
Volume= 180ft^3
The expression for the volume of a sphere is given as
Volume=4/3πr^3
substitute
180=4/3*3.142*r^3
180=12.568/3*r^3
180=4.189*r^3
r^3= 180/4.189
r^3= 42.969
cube root both sides
r= ∛ 42.969
r= 3.50ft
Hence the radius is 3.50ft
