Answer:
x^2 + y^2 = 3^2
Step-by-step explanation:
Use the standard equation of a circle with center at (h, k) and radius r:
(x - 0)^2 + (y - k)^2 = 3^2, or
Answer: 38.5 cm^2
Length of wire = 7*2 + 4*2 = 22 cm
Radius of Circle = 22/(2pi) = 3.5 cm
Area of Circle = (3.5)^2*pi = 38.5 cm^2
Row two (-4, 0)
Because of the zero in the y the point does not move from the x-axis.
The answer is d 1/6th
