Answer:
Step-by-step explanation:
The equation for the area of a circle is A=.
A=area
r=radius
We were given the diameter of the circle not the radius, so we need to solve for the radius.
Radius=(1/2)Diameter So,
(1/2)6=3mm
Now we can solve for the area.
3^2(3.1415926)=28.2743mm
Now round to two decimal places.
28.27mm
For x such that 0 < x < , the mathematical expression is:
<u>Given the following data:</u>
In Trigonometry, you should take note of the following mathematical expression:
Therefore, we can obtain the following:
...equation 1.
...equation 2.
Substituting the equations respectively, we have:
Taking the square roots, we have:
Therefore, for x such that 0 < x < , the expression is:
