Question

Find the volume of the composite solid if the diameter of the cone is 18.6 inches and the diameter of the cylinder is 22.5 inches. Round your answer to the nearest hundredth. A. 5,456.68 in3 B. 5,867.88 in3 C. 6,771.79 in3 D. 21,826.72 in3

Answer 1

cylinder volume is pi*r^2*h = 3.14*11.25^2*12.07=4799.126
cone height is h=sqrt(g^2-r^2)=sqrt(11.8^2-9.3^2)=7.26
cone volume is pi*r^2*h/3 = 3.14*9.3^2*7.26/3=657.553

total volume is 5456.68
