Question

What is the diameter of the following circle? (x-6)^2 + (y-7)^2 =25

Answer 1

d = 10

Explanation:

The standard form of an equation of a circle:

`(x-h)^2+(y-k)^2=r^2`

(h, k) - center

r - radius

We have the equation:

`(x-6)^2+(y-7)^2=25`

h = 6, k = 7, r = √25 = 5

The diameter d = 2r → d = 2(5) = 10
