How is the area of a semicircle found?
1 answer:
Answer:
(A) Take half the area of the whole circle.
Step-by-step explanation:
A semi-circle is half of a circle, thus the area of circle is given by:'
Area of circle=, where r is the radius of the circle.
Since, A semi-circle is half of a circle, therefore area of the semi circle is also half of the circle, therefore
Area of semi circle=
Thus, the area of the semi circle can be found by taking half the area of the whole circle.

<h2>Hello!</h2>
The answer is: The point (0,0) is part of the solution.
<h2>Why?</h2>To find which point is part of the solution of the inequality, we need to evaluate each of the given points. If the inequality is satisfied, then the point is part of the solution, otherwise, if the inequality is not satisfied, the point is not part of the solution.
We are given the inequality:
So, evaluating we have:
- First point (-2,1)
Now, since 1 is not less or equal to -1, the point (-2,1) is not part of the solution.
- Second point (1,3)
Now, since 3 is not less or equal to 2, the point (1,3) is not part of the solution.
- Third point (-4,2)
Now, since 2 is not less or equal to -3, the point (-4,2) is not part of the solution.
- Fourth point (0,0)
Now, since 0 is less than 1, the point (0,0) is part of the solution.
Hence, we have that the point (0,0) is part of the solution.

Answer:
Step-by-step explanation:
Orginal equation:
So lets do this step by step.
First, lets add to both sides of the equation!
This gives us:
Then, when we put this into exponential form, we get:
This then equals:
This can be simplfied into:
Then we can add 32 to both sides, and subtract x from both sides to get the variable and number each on their owns ide:
Finally, we can divide 33 by 7 to get:
Hope this helps! :3
