a circle has its center at (1, 4) and a radius of 2 units. what is the equation of the circle?

(x − 1)2 + (y − 4)2 = 4

(x + 2)2 + (y + 4)2 = 2

(x + 1)2 + (y − 4)2 = 4

(x − 1)2 + (y − 4)2 = 2

A.

Step-by-step explanation:

We have been given that a circle has its center at (1, 4) and a radius of 2 units. We are asked to write the equation of the given circle.

Since we know that the center-radius form of circle equation is:

, where (h,k) is the center of circle and r is radius of circle.

Upon substituting our given values in above format we will get,

Therefore, the equation of our given circle is and option A is the correct choice.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
