49 unit because and any subsequent words was ignored because we limit queries to 32 words.

Answer 2

Answer:

The area of a circle:

$A = 12$

Step-by-step explanation:

-First find the perimeter of a triangle by adding the three measures from the sides of a triangle (2 units, 5 units, and 5.39 units):

Finding the perimeter of a triangle:

$2 + 5 + 5.39 = 12.39$

Perimeter = $12.39$ units

-After have the perimeter of a triangle, find the area of circle by using this formula:

$A = \frac{C^{2}}{4\pi }$

-Since circumference equals the perimeter of the triangle, then the circumference would be $12.39$. After you have the circumference, apply it for the formula:

$A = \frac{12.39^{2}}{4\pi }$

Then, solve for area:

$A = \frac{12.39^{2}}{4\pi }$

$A = \frac{1535121}{40000\pi } \approx 12.2$

Since $12.2$ can't be rounded to the nearest whole number, the answer will be written as:

$A = 12$

So, the area of a circle is $A = 12$ .
