We know that the area of a circle is represented by the equation:
And we know that the diameter of a circle is twice the radius:
So if we know that the diameter is 13m, we can solve for the radius:
-->
Then we can plug in this radius into the equation for the area of a circle, using 3.14 to approximate the value of pi:
So now we know that the area of the circle is 132.665 square meters.
It can be rounded to 270,000 because 4 is less than half. (4 and below drops it down)

<h3>Answer: 72 degrees</h3>
================================
Explanation:
Use the inscribed angle theorem to go from inscribed angle D = 66 to 2*66 = 132. The central angle is double that of its corresponding inscribed angle.
This means arc ABC has measure 132 degrees.
The minor arc BC is 97 degrees, so
(minor arc AB) + (minor arc BC) = arc ABC
(minor arc AB) + (97) = 132
minor arc AB = 132-97
minor arc AB = 35
and
(minor arc DA) + (minor arc AB) = arc DAB
(109) + (35) = arc DAB
144 = arc DAB
arc DAB = 144
Now use the inscribed angle theorem again. Cut the arc measure DAB in half to get its corresponding inscribed angle measure (angle C)
144/2 = 72
<h3>angle C is 72 degrees</h3>
Answer:
a) S=8667.30.
b) S=39576.93.
Step-by-step explanation:
We know that the future value S that accumulates from an initial investment of $2000 is
a) If r=6%, we get:
Therefore, we get that S=8667.30.
b) If r=12%, we get:
Therefore, we get that S=39576.93.
If the interest rate is higher, we also get S higher.
