Me with this question its urgent its about completing a equation

(x - 2)² + (y +8)² = 49

Step-by-step explanation:

Points to remember

Equation of a circle passing through the point (x₁, y₁) and radius r is given by

(x - x₁)² + (y - y₁)² = r ²

To find the radius

It is given that, center of circle = (-5, -8) and passes through the point (2 -8)

By using distance formula,

r = √[(2 --5)² + (-8 --8)²]

 = √7²

r = 7

To find the equation of the circle

Here (x₁, y₁) = (2, -8)

Equation of circle is,

(x - x₁)² + (y - y₁)² = r ²

(x - 2)² + (y - (-8))² = 7²

(x - 2)² + (y +8)² = 49

The equation of circle is .

Step-by-step explanation:

The standard form of a circle is

             .... (1)

where, (h,k) is the center of the circle and r is the radius.

It is given that the center of the circle is (-5,-8). it means h=-5 and k=-8.

The circle passes through the point (2,-8). So, the radius of the circle is the distance between point (-5,-8) and (2,-8).

Substitute h=-5, k=8 and r=7 in equation (1), to find the equation of circle.

Therefore the equation of circle is .

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

it is 570
