The area of the circle is given by , so in your case it is squared feet.
The whole center is given by a center angle of 360°, but you're only interested in the 152° sector.
So, we have the following proportion:
which means
solving for x, we have
2.
Given the center and the radius , the equation of a circle is
Plug your values to get
Which you can rewrite as
Or, if you prefer,
Hello there! :-)
The formula for finding the area of a circle is
Notice that only the radius is squared.
We are given the radius of the circle: 21 cm.
We plug the value of r into the formula:
- A=π(21)²
- A=π(441)
- A=1,385 cm
Hope this helps. Use the comment section to clarify your doubts.

Hello!</h2>
The answer is: True.
<h2>Why?</h2>
A counterexample is a way that we can prove that something is not true about a mathematical equation or expression, it's also considered as an exception to a rule.
So:
Then, evaluating we have:
Hence, we can see that the equation is not fulfilled, so, 45° is a counterexample for and the answer is true.
Have a nice day!
To simplify this expression, you have to distribute. Distribution is when you multiply the outside number by the inside ones. For example, if I distributed 2(4 + 6), I would get (2 × 4) + (2 × 6).
So if we distribute your expression, we'd get:
(-3 × -4y) + (-3 × 3) + 7y
Now simplify:
12y + -9 + 7y
Once more, simplify:
19y - 9
The answer is A
Answer:
20m
Step-by-step explanation:
the 4m and 2m on the right can make a rectangle for 8m, then you can make another rectangle on the left side with the remaining 4m (from the 8m side) to make 8m so now were at 16, the triangle remainse, the length is 4m and the height is 2m making 8/2 or 4
16+4 = 20m
