14. height = volume/ ( length x width)
Height = 224/ ( 2x8)
Height = 224/16
Height = 14 inches.
15. height = volume/ area of the top(circle)
Area of top = pix r^2 = 3.14 x 4 = 12.56 square inches.
Height = 62.8/12.56 = 5 inches
16. Volume/ height = area of top(circle)
169.56/ 6 = 28.26 square inches
Area = pi x r^2
28.26 = 3.14 x r^2
Divide both sides by 3.14
R^2 = 28.26/3.14 = 9
Take the square root of both sides
R = sqrt(9)
R = 3
Radius = 3 inches
