Question

What is the diameter of the circle x^2+(y+4/3)^2=121?

Answer 1

22 units.

Explanation:

That would be 2 * radius and

radius = √121 = 11.

So the diameter =- 22.

Answer 2

The diameter is 22

Explanation:

The equation of a circle is in the form

(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius

x^2+(y+4/3)^2=121

(x-0)^2+(y- -4/3)^2=11^2

The center is at ( 0,-4/3) and the radius is 11

The diameter is 2 * r = 2*11= 22
