Answer:
Center: (9, 4)
Radius: 20
Explanation:
(x - 9)² + (y - 4)² = 400
The Circle Formula:
(x - h)² + (y - k)² = r²
where (h, k) is center points, r is radius
Rewrite the equation:
(x - 9)² + (y - 4)² = 20²
Identify following:
h = 9, k = 4, radius = 20
Answer:
156
Step-by-step explanation:
7 * 18 = 126
126 +45 / 3 * 2
45 / 3 = 15 * 2 = 30
126 + 30 = 156
Because 1/2 = 3/6
therefore you have to multiply 1/6 by 3 to achieve that.
I'm not going to do your homework for you. but sub in 0 for y and solve. <span />
