Answer:
64π in²
Step-by-step explanation:
The area of a circle is given by the formula ...
A = πr²
where r is the radius.
The radius of a circle is half the diameter. For the circle shown, the radius is ...
r = d/2 = (16 in)/2 = 8 in
Then the area is ...
A = π(8 in)² = 64π in²
_____
Often, units are left off, so the appropriate choice might be 64π.
_____
If you want to be technically correct (at the expense of getting your answer marked wrong), you can select "None of the above." That is because none of the offered choices have the correct units: square inches. You may want to discuss this with your teacher.
Answer:
36
Step-by-step explanation:
Quadrilateral's angels always add up to 360. Thus, 2x+5x+6x+7x=360
20x=360 (divide both sides by 20)
x = 18
To find the smallest angle, plugin x into 2x.
2(18)=36

For this case we have a logarithmic equation in which we must find the value of the variable x. For this we must apply properties of logarithm. By definition we have:
is equivalent to 
Applying the definition, we have that: 
must be equivalent to: 
Solving the resulting equation we have:
Clearing x:
Thus, the value of x is given by 95.
