The diameter of the circle can be found by using the distance formula with the two points given...

d^2=(4--10)^2+(6--2)^2

d^2=14^2+8^2

d^2=260

d=√260

d=2√65

Since the radius is just half of the diameter, r= √65

The center of the circle will just be the midpoint (the average of the coordinates of the two endpoints) of the two points given so:

c=(-10+4)/2, (-2+6)/2

c=(-3,2)

The standard form of the circle is:

(x-h)^2+(y-k)^2=r^2, where (h,k) is the center of the circle so we can say:

(x+3)^2+(y-2)^2=65

What is the radius of a circle with circumference of 50 cm? Round your answer to the nearest whole number. Use π = 3.14.
RoseWind [281]

Answer:

8 is the answer

Step-by-step explanation:

the equation is r = C/2*3.14

2*3.14=6.28

Because your C is 50  you do 50/6.28 and when you do that you get 7.962 (rounded) and then we round for the whole # so 8.
