The area of a square is the square of the length of its side. Here, we're told that the side of each square is equal to the radius (r) of the circle. Then the area of each square is
.. Asquare = r^2
There are 3 of them, so their total area is
.. Aall_squares = 3*r^2
The area of a circle is given by the formula
.. Acircle = π*r^2 . . . . . where r represents the radius of the circle
Fernie wants to compare the area of the 3 squares to that of the circle. We know that the value of π is about 3.1416, a little more than 3, so we have
.. Aall_squares = 3*r^2
.. Acircle ≈ 3.1416*r^2
We notice that 3.1416 is more than 3, so the area of the circle is greater than the area of Fernie's 3 squares.
___
It is not clear to me that Fernie's drawing will explain the formula A = π*r^2, unless it can somehow be used to show that the parts of each square that are outside the circle add up to an amount that is slightly less than the uncovered part of the circle.
Answer:
Its the second option. 742.5
Answer:
6:5
Step-by-step explanation:
6:5 is already at its simplest form.
You cannot simplify 5 anymore than it is.
But, it can be written as 1.2 in decimal form (rounded to 6 decimal places).
Though, I do not believe that is the answer you are looking for.
X+ 5 < 17 =answer 1
-5 -5
x<12 =answer 2
Answer is -3/4
Start with putting parentheses on the given numbers for these variables
Remove parentheses(When there is a in front of an expression in parentheses, the expression remains the same)
Reduce the numbers with the greatest common factor(3)
Calculate the difference 1 -7/4
Alternative form: -0.75
