Round answers to 2 decimal places. State your answers in the correct units of measurement. c) Find the surface area and volume of a spherical ball bearing with a diameter of 25mm. Round answers to 2 decimal places. State your answers in the correct units of measurement. d) Find the surface area and volume of a solid frustum of a cone of large diameter 500mm, small diameter 210mm and perpendicular height 717mm. Round answers to 2 decimal places. State your answers in the correct units of measurement. Evidence you must produce for this task You should use your allocated values for 829 and 717 that can be found in appendix 1 at the rear of this assignment to complete the 4 questions above. Ensure that you show all working and solutions should be clear, follow appropriate mathematical procedure and appropriate units should be stated with all answers. Criterion To achieve the criteria, you must show that you are able to: reference Use standard formulae to find surface areas and volumes of regular solids for three P7 different examples respectively
