Find the radius of a circle, given that the center is at (3,-3) and the point (7,6) lies on the circle.

Alenkasestr [34]

Answer:

$\large\boxed{radius=\sqrt{97}}$

Step-by-step explanation:

The radius is the distance between the center and any point on the circle.

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have the center (3, -3) and other point on the circle (7, 6).

Substitute:

$r=\sqrt{(6-(-3))^2+(7-3)^2}=\sqrt{9^2+4^2}=\sqrt{81+16}=\sqrt{97}$

Explain why (4, 1) is not a solution to the equation y=3x+1

nexus9112 [7]

In (4, 1) 4 represents x, and 1 represents y

y = 3x + 1

1 = 3(4)+1

1 = 12 + 1

1 ≠ 13 ← sides are not equal so (4, 1) is not a solution to y=3x+1
