What is the equation of a circle with a center located at (4, -1) and a radius of 9?
1 answer:
Answer:
(x-4) ^2 + (y+1)^2 = 81
Step-by-step explanation:
The equation of a circle is given by
(x-h) ^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x-4) ^2 + (y--1)^2 = 9^2
(x-4) ^2 + (y+1)^2 = 81

Answer:
B. 785 M
Step-by-step explanation:
Circumference = 2*pi*r
C = 2 * pi * 125
C = 250pi This is the exact answer
Now approximating with pi as 3.14
C = 250 (3.14)
C = 785
