A circle is defined by the equation given below.

tatyana61 [14]

Answer:

(1/2, 1)

Step-by-step explanation:

x² + y² − x − 2y − 11/4 = 0

x² − x + y² − 2y = 11/4

Complete the squares.

x² − x + 1/4 + y² − 2y + 1 = 11/4 + 1/4 + 1

(x − 1/2)² + (y − 1)² = 4

The center of the circle is (1/2, 1) and the radius of the circle is 2.

What is the exact area of a circle with a diameter of 20 cm?

Kisachek [45]

Hi there! The answer is 100πcm^2

The radius of a circle can be found by dividing the diameter by 2. In other words : the radius is half of the diameter.
Therefore, the radius of a circle with a diameter of 20 cm is 10 cm.

The exact area of a circle can be found using the following formula:
$a = \pi \times \: {r}^{2} \\ with \\ a = area \\ r = radius$

In order to find our answer, we need to plug in the data from the question.
$a = \pi \: \times {10}^{2} = 100\pi$

Hence, the answer is 100πcm^2.
