Answer:
r=1/π
Step-by-step explanation:
Area of the circle is defined as:
Area = πr²
Derivating both sides
=2πr
=
x
= 2πr
If area of an expanding circle is increasing twice as fast as its radius in linear units. then we have :
=2
Therefore,
2πr
= 2 
r=1/π
No, if it was the inequality would be x ≤ 3 not x < 3
Answer:
The remainder is -64
Step-by-step explanation:
Given

Divided by 
Required
Determine the remainder
Equate
to 0

Solve for x

Using remainder theorem, substitute 8 for x in 
So, we have:

Evaluate all exponents

just did the test and got it right its /x + 2
Step-by-step explanation:
just did the test i cant make the simble though but the right answer is the one where the line is only above the x oh wait actually i see your questions know my delete key broke soooo its the 2nd option
