What is the center of the circle with the equation (x-1)^2 +(y-3)^2=9

(1, 3)

Step-by-step explanation:

Equation of a circle: (x - h)² + (y - k)² = r², where (h, k) is the center

h = 1, k = 3 --> the center is (1, 3)

it could be 1,3 and more others to create a cylinder.

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
