Answer:
The value of n must be a positive number.
Step-by-step explanation:
Area of a square is given by where
is the side of the square.
Now, given the area of the square is .
OA) If the area had been zero, i.e., then it means that there is no square at all.
OB) Also, it can not be any other number other than zero as this can include negative numbers as well. And an area being negative makes no sense. (OD) is eliminated as well.
So, the area should be positive.
Given:
Area of a circle, A=50.265 sq. units.
Radius of circle, r = 4 units.
To find:
The value of π to the nearest thousandth.
Solution:
Formula for area of a circle is
Now, using expression, we can find the value of π.
Approximate the value to the nearest thousandth (three digits after decimal).
Therefore, the approximated value of π is 3.142.
