Answer:
The answer to your question is letter C
Step-by-step explanation:
From the graph, we get the center and the radius
- The center is the point shown in the graph and its coordinates are (2, -1).
- The length of the radius is 4 units, from the center we count horizontally the number of squares (4)
Substitution
(x - 2)² + (y + 1)² = 4²
or (x - 2)² + (y + 1)² = 16
1230 1203 1302 1320 1032 1023 2130 2103 2301 2310 2032 2023 3210 etc
Radius is half of diameter.
Circumference can be found using the equation C=2(pi)r or C=(pi)d.
r=radius, d=diameter
(pi) is about 3.14 or 22/7
