Answer:
i think it's 2/5
Step-by-step explanation:
- - Solve:
To find the volume of a sphere:

3.14≈π
Now since its telling us to use π, then we do our formula by multiplying by π.
π=3.14 (Approximate amount)
So:

So you are correct.
When Radius=9, you plug in for R. :)
3: 8 4: 11 6: 15 7: 17 8: 9 10: 7 11: 13 12: 9
Answer:
x ={0; - 1 ; 2 ; 1}
Step-by-step explanation:
x¹³-2x¹²-x¹¹+2x¹⁰=0
x¹⁰(x³-2x²-x+2)=0
x¹⁰(x+1)(x-2)(x-1)=0
x¹⁰=0 ∨ x+1=0 ∨ x-2=0 ∨ x-1=0
x=0 x= - 1 x= 2 x= 1
Answer:
1/5
Step-by-step explanation:
In order to find the answer, we need to isolate the "n."
Get 5 to the other side by dividing both sides by 5
(n-1/10)= 1/2 ÷(5)
Multiply the 2 and the 5 of the equation.
(n-1/10)= 1/10
Next, move the fraction on the left side, to the right.
n= 2/10
Reduce.
n= 1/5
