Answer:
868 m³
Step-by-step explanation:
Volume = Difference of cones
V = ⅓(pi×r²h)
Volume of cone with base Circle O:
h = 8.2+8.2 = 16.4 m
V1 = ⅓(pi×7.6²×16.4)
V1 = 991.97
Volume of cone with base Circle A:
V2 = ⅓(pi×3.8²× 8.2)
V2 = 124 m³
Volume = V1 - V2
991.97 - 124 = 868 m³
Answer:
i cant see it very well it is too small can you zoom it in some thx :)
Step-by-step explanation:
You would find the sign if the signs are not the same if you are dividing or multiplying its negitve if its the same its positive
Supplementary angles
x+20+5x+10=180
6x+30=180
6x=150
x=25
