Answer:
486 pi or 1526.81 km^3
Step-by-step explanation:
The volume of a hemisphere is found by the equation: 2/3(pi*r^3)
Insert the radius 9 km into the equation, 2/3(pi*9^3) -> and solve
2/3(729pi)
(1458/3) pi
486 pi OR multiply by 3.1415926 and get 1526.81 km^3
Answer: G
Step-by-step explanation: the rate of change is constant, making it a proportional relationship
Each digit can be one of {1, 3, 5, 7, 9}, so there are 5 choices for each. Then there are 5•5•5 = 5³ = 125 integers containing only odd digits, which means they make of 125/900 ≈ 14% of them.
4 + 2(3x - 7) + 5x
Distribute
4 + 6x -14 + 5x
Combine like terms
-10 +11x or 11x - 10
