What is the circumference of the circle whose equation is (x - 9)2 + (y - 3)2 = 64?

8p
4p
64p
16p

Step-by-step explanation:

We know that standard equation of a circle is given by :-

, where r is the radius of the circle.

The given equation of the circle is . it can be rewrite as ,

When we compare the given equation to the standard equation of the cicrl;e, it can be seen that the radius of the circle = 8 units.

Now, the circumference of a circle is given by :-

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

c. side angle side. u shares the same sides
