Estimate the volume of material in a cylindrical shell with length 40 in., radius 3 in., and shell thicknessw in, _ 0.5 in. The estimated volume of material is :J in.3 (Type an integer or decimal rounded to the nearest tenth as needed.)

The diameter of a sphere is measured as 120 :i: 2 cm and the volume is calculated from this measurement.
Estimate the percentage error in the volume calculation. There is approximately D% error in the volume
calculation. (Simplify your answer.)
