Answer:
A = 254.5 mm^2
Step-by-step explanation:
The radius of this circle is 9 mm.
Using the formula A = (pi)r^2, we find the area of this particular circle to be:
A = (pi)(9 mm)^2, or
A = 254.5 mm^2
We saw under Functional Notation that y = 3x + 2 and f (x) = 3x + 2 can be interpreted as equivalent notations, where y has been replaced by f (x), or y = f (x). In y = 3x + 2, we see “y as a function of x”
The answer would be X=-26/15
The expression that represents the shaded region is 1/4
<h3>How to determine the expression?</h3>
The figure represents the given parameter
From the figure, we can see that:
- The complete figure is a circle
- Part of it is shaded
- The remaining part is unshaded
From the figure, we can also see that:
Shaded region = 1/4 of the whole circle
In this case, we set the whole circle to 1
So, we have
Shaded region = 1/4 of 1
Rewrite as
Shaded region = 1/4 x 1
Evaluate
Shaded region = 1/4
Hence, the expression of the shaded region is 1/4
