I need help with the equation.
natulia [17]

Answer:

(x - 3)² + (y + 9)² = 25

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

Given area = 25π , that is

πr² = 25π ( divide both sides by π )

r² = 25 ( take the square root of both sides )

r = \sqrt{25} = 5

With centre (h, k) = (3, - 9 ) and r = 5 , then

(x - 3)² + (y - (- 9) )² = 5² , that is

(x - 3)² + (y + 9)² = 25

Pls helpppppp thanks!!!!!!!<br> :)
Lena [83]

Answer:

If i did this right the answer would be 69

I converted the inches to feet (might be my first mistake)

so i get 2.5 X 1 X 1 to get 2.5

i then multiply that by 62.4 to get 156

then 225-156 = 69
