Question

(15 POINTS) (SHOW WORK) FIND THE RADIUS OF THE CIRCLE

Answer 1

7

Explanation:

(x-x)^2 + (y-y)^2 =r^2

r^2=49

r=7

Answer 2

Given the equation, the radius of the circle is 7.

Explanation:

We are given the equation, x² + y² = 49.

In order to find the radius, we have to calculate the square root of 49. This is because the original form of the equation is x² + y² = r².

`√(49) = 7`

So, the radius of the circle is 7.
