Answer:
V = 1/3 • π • radius cubed • height
If the volume is is 16π and the height is 3, then 16π = 1/3 • π • r cubed • 3
16π ÷ (1/3 • π • 3) = 16
radius squared = 16 √16 = 4, so radius = 4
You can also check: 1/3 • r cubed • 3 = 16 The only value left to multiply is π
Step-by-step explanation:
Answer:
If you need the answer as f by simplifying both sides of the equation and then isolating the variable, the answer would be:
Or, if you need to evaluate the function itself, the answer would be:
Answer:
The number '1' is called the 'multiplicative identity' of a number '-12/13' because it does not change the number '-12/13' after getting multiplied by it.
Therefore, option (B) is true.
Step-by-step explanation:
We know that when a number let say 'n' get multiplied by '1', it remains unchanged.
i.e.
The number '1' is called the 'multiplicative identity' of a number 'n' because it does not change the number 'n' after getting multiplied by it.
Given the number
-12/13
Multiply the number '-12/13' by '1'.
i.e.
-12/13 × 1 = -12/13
1 × -12/13 = -12/13
Thus, the number '1' is called the 'multiplicative identity' of a number '-12/13' because it does not change the number '-12/13' after getting multiplied by it.
Therefore, option (B) is true.
Answer:
20 days
Step-by-step explanation:
It takes 12 men 5 days to complete a job. Work out how many days it would take 3 men to complete the same job.
12 * 5 = 60
60/3 = 20
It will take 3 men 20 days to do the same job
Step-by-step explanation:
Triangle 1 can have 30°, 75° and 75° angles whereas Triangle 2 can have 30°, 30° and 120° angles.
Since they do not have all 3 congruent angles, they are not similar.
