The circle below is centered at the point (4,1) and has a radius of length 2. What is it’s equation?
2 answers:
Answer:
B
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k ) = (4, 1) and r = 2, hence
(x - 4)² + (y - 1)² = 4 → B
Answer:
Option B:

Step-by-step explanation:
Given
Centre = (h,k) = (4,1)
Radius = r = 2
The standard equation of circle is:

Putting the values of h,k and r

Hence, the correct option is option B

Answer:
200 meters
Step-by-step explanation:
a² + b² = c²
c² = 120² + 160²
c² = 14,400 + 25,600
c² = 40,000
√(c²) = √(40,000)
c = 200
Answer: 200 meters
