The formula for the area of a circle is A = πr^2
Since we know the length of the square is 7cm and the circle fills the full length, 7cm is the diameter.
To get the radius you divide the diameter by 2.
7/2 = 3.5
So, your radius is 3.5.
Now your formula looks like this: A = π(3.5)^2
Next you would square 3.5 because (3.5)^2 means to multiply 3.5 by 3.5
3.5^2 = 12.25
Now, you just multiply 12.25 by the approximate version of pi, which is 3.14.
12.25*3.14 = 38.465
Now, that you have the area of the circle, you subtract it from the area of the square.
If you already haven't figured out the area of the square it is 49 cm.
This is because the formula for the area of a square is A = bh or A = lw
Since the length (l) or base (b) is 7, we know that the other sides are 7 because squares have equal sides.
So now we subtract 38.465 from 49 and we get 10.535 which rounds to 10.54
So, your final answer is D. 10.54 cm^2
Hope this helps!
Well, keep in mind that the domain of a function is the entire set of possible values of the independent variable. To make it more clear, the domain is the set of all possible x-values, which will make the function work, and with real y-values as the output. So, the range would be the set of all of the second elements of an ordered pair (y-coordinates).
If you made a T chart like the picture you have above, you would have to put x (age of person) and y (books read).
So,
x = age of person
y = books read
It depends on what type of shape. What shape are you trying to find surface area for?
Answer:
x=34
Step-by-step explanation:
When we look triangle SQR, we have angles 3x and 68, we know that sum angles of triangle is 180.
<R=180-(3x+68)
Now, we look at the PQS:
<PQS=180-68=112°
Then :
<PSQ=180-(112+x)=68-x
Then we have :
Angles PSR= 68-x+3x=68+2x and angles TSU=4x.
We have that
PSR=TSU
68+2x=4x
4x-2x=68
2x=68
x=34
