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
