Hi there! :)

Answer:

$\sqrt{\frac{A}{\pi } } = r$

Step-by-step explanation:

Formula for the area of a circle:

$A = \pi r^{2}$

Rearrange the equation in terms of "r":

Divide 'π' from both sides:

$\frac{A}{\pi } = r^{2}$

Take the square root of both sides:

$\sqrt{\frac{A}{\pi } } = r$

Solve the system of equations algebraically.<br><br> {Y=(x-2)^2+2<br> {Y+4=3x

nikdorinn [45]

Answer:

(5, 11) and (2, 2)

Step-by-step explanation:

y = (x-2)² + 2

y + 4 = 3x

(x-2)² + 2 + 4 = 3x

x² - 4x + 4 + 6 = 3x

x² - 7x + 10 = 0

(x - 5)(x - 2) = 0

x - 5 = 0, x = 5

x - 2 = 0, x = 2

y = (5-2)² + 2 = 11

(5, 11)

y = (2-2)² + 2 = 2

(2, 2)
