Question

The figure is made up of a cylinder and a half sphere.What is volume of the composite figure? Use 3.14 for r. Roundthe the nearest hundredth.4 mm7 mmRecall the formulas v Bh and V

Answer 1

the volume of cylinder = area of base time height

V_cylinder = pi*4^2 = 16pi

V_semisphere = (4pir^3/3)/2 = (4pir^3)/6 = 4pi64/6 = 256pi/6 = 128pi/3

V_composite figure = 16pi + 128pi/3 = (48pi +128pi)/3 = 176pi/3

hope helped
