Review the graph of circle A. On a coordinate plane, a circle has center A (1, 1) and point B (5, 4) is on the edge of the circle. A line goes from point A to point B. Which equation represents circle A? (x – 1)2 + (y – 1)2 = 5 (x + 1)2 + (y + 1)2 = 5 (x – 1)2 + (y – 1)2 = 25 (x + 1)2 + (y + 1)2 = 25

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.

300pi

step-by-step explanation:

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
