Answer:
575.8 cubic cm
Step-by-step explanation:
V(cone) = 1/3· π · r² · h
V = 1/3 · π · 25 · 12
V = 4(25)π or 100π = 314
V(half-sphere) = (4/3 · π r³)/2
V = (4/3π · 125) = 261.8
Answer:
x=7

Answer:
1/3
Step-by-step explanation:
Simplify the following:
1 - 2/3
Put 1 - 2/3 over the common denominator 3. 1 - 2/3 = 3/3 - 2/3:
3/3 - 2/3
3/3 - 2/3 = (3 - 2)/3:
(3 - 2)/3
3 - 2 = 1:
Answer: 1/3
