The area of the circle can be formulated as A = πr². So if the radius is 2 units, then you simply use it and multiply everything. 

First you substitute the data:

A = πr²
A = (3.14)(2)²

Then multiply everything and get to the answer of A = 12.56 square units

Thus, the answer is 12.56 square units.

Verify this identity: secx-cosx = 1-cos^2x/cosx
Sauron [17]

Step-by-step explanation:

sec x − cos x

Secant is the inverse of cosine:

(1 / cos x) − cos x

Find the common denominator:

(1 / cos x) − (cos² x / cos x)

Subtract:

(1 − cos² x) / cos x

Circle Center Formula: (x - h)² + (y - k)² = r²

  • <em>(h, k) </em>is center
  • <em>r</em> is radius

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

<em>(h, k)</em> = (8, 10)

<em>r</em> = 6

<u>Step 2: Find Equation</u>

  1. Substitute in variables [Center Circle Formula]:                                             (x - 8)² + (y - 10)² = 6²
  2. Evaluate exponents:                                                                                         (x - 8)² + (y - 10)² = 36

Can someone help me please its geometry.
mars1129 [50]

The figure showing the construction is given below.

Steps for the construction of a circle through three points not on a straight line are as follows:

1. To create two lines, connect the points.

2. Create the line's perpendicular bisector.

3. Create the opposite line's perpendicular bisector.

4. The circle's center is where they intersect.

5. Draw your circle by placing the compass on the center point and adjusting its length to reach any point.

What happens if the points are parallel?

The circle traveling through all three points will have an infinite radius if the three points are collinear, or all situated on a straight line. Therefore, a practical circle cannot traverse three collinear locations. The two radii would be parallel and would never come together at a center if you tried the construction. We may claim that they do cross mathematically but at infinity.

Hence, after following the steps we obtain the circle.
