Answer:

V=11858.98

Step-by-step explanation:

V=r^2*pi*h

first find r

r=d/2

d=1.4(19.75)

d=27.65

r=27.65/2

r=13.825 ft

plug into volume equation

V=13.825^2*pi*19.75

V=11858.97771

V=11858.98 ft^3
Answer: Volume = 11,898.98

Find radius: 1.4*19.75=27.65/2=13.825

Find volume: πr^2h= π*13.822*19.75=11858.97771

Round to get 11,898.98
