Question

if one end of the diameter of a circle with Centre as origin is - 2,10 then length of diameter of the circle is​

Answer 1

Answer:

20.39

Step-by-step explanation:

radius = distance from origin to 2,10 = 10.19

diameter = 20.39

Answer 2

Answer: 4√26 unit

Step-by-step explanation:

Origin (0,0)

Center  =  (-2,10)

Distance between origin and center is radius of circle

Therefore by heron's formula

$d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$r= \sqrt{(-2-0)^2+(10-0)^2} = \sqrt{4+100} = \sqrt{104} = 2\sqrt{26}$

Diameter of circle = 2 x radius= 2 x 2√26 = 4√26 unit

Hence the diameter of circle is 4√26 unit
