Answer:
perimeter = 8
Step-by-step explanation:
We require to calculate the area (A) of the circle
A = πr² ← r is the radius
circumference = 4π = 2πr, hence
2πr = 4π ( divide both sides by 2π )
r = 2, hence
A = π × 4 = 4π
The area of the square is therefore 4π and area = s² ← s is the side length
s² = 4π ( take the square root of both sides )
s = = 2
, hence
perimeter = 4 × 2 = 8
Answer:
<u>answer is C ( </u><u> )</u>
Step-by-step explanation:
so here is how you do it.
first you need to find out what is
which is the same as 3 X 3 X 3 X 3 X 3 X 3 X 3 X 3
the answer to that is 6,561
then you have to square root that
which looks like this
which is 81
which means that you have to find the same expression that equals to 81
I then did (C) to see if the answer will be 81 and it is. so your answer is C
