#1 is A & B (points connect)
#2 is A & B & D (because they all touch)
#3 I don't know
#4 I think it's G, C, & F
#5 D
Answer: (x - 4)^2 + (y + 3)^2 = 4
Step-by-step explanation:
The equation of circle given the center and the radius: (x - h)^2 + (y - k)^2 = r^2
Center : (h, k)
Radius: r
Given: center (4, -3), h = 4 and k = -3; radius 2, r = 2
Substitute into formula: (x - h)^2 + (y - k)^2 = r^2
(x - 4)^2 + (y - (-3))^2 = 2^2
Answer: (x - 4)^2 + (y + 3)^2 = 4
Your answer to your problem is -1/3
Answer:
254.47
Step-by-step explanation:
First you have to know the formula for the area of a circle which is:
<h2>
</h2>
In the word problem it gives us the radius of a pancake which is 9 cm, so we just need to plug it into<em> r </em>in our formula:
<h2>
</h2><h2>
</h2>
≈ 254.47
