Sagot :
first find volume of inner cone and outer cone then subtract inner from outer
so inner=1/3 (base area) times height
1/3 times (pi times 10^2) times 6
1/3 times 3.14 times 100 times 6
1/3 times 314 times 6
314 times 6/3=628=volume of inner cone
outer cone
base area=314
1/3 times 314 times 14=1456.33
so subtract 628 from 1456.33
1456.33-628=837.3 cm^3
so inner=1/3 (base area) times height
1/3 times (pi times 10^2) times 6
1/3 times 3.14 times 100 times 6
1/3 times 314 times 6
314 times 6/3=628=volume of inner cone
outer cone
base area=314
1/3 times 314 times 14=1456.33
so subtract 628 from 1456.33
1456.33-628=837.3 cm^3
Answer: 1456.33-628=837.3 cm^3
