Write an equation of the circle whose radius is 3 and whose center is (-1.6).

 (x + 1)² + (y - 6)² = 9

Step-by-step explanation:

The equation of a circle is: (x - h)² + (y - k)² = r²

Given: (h, k) = (-1, 6), r = 3

Input the given values into the equation:

(x - (-1))² + (y - 6)² = 3²

(x + 1)² + (y - 6)² = 9

answer: sorry but i need points

step-by-step explanation:

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
