Answer:
Volume = 6467.492mm³
Surface area = 1332.035mm²
Step-by-step explanation:
volume of a cone is r²h. V=10²(24)=7539.822mm³
volume of a sphere is 4/3r³. V=4/3(8³)=2144.66mm³
Since it's a half of a sphere, it would be 1072mm.33³
7539.822-1072.33=6467.492mm³
Surface area of a cone is r(r+√h²+r²)=1130.97
area of a circle= r²=201.06
surface area of a sphere is 4r²=804.25
Since it's a half sphere, it would be 402.125
1130.97-201.06+402.125=1332.035mm²
