Question

16. If one end of the diameter of a circle with centre as
origin is (-2, 10), then the length of diameter of the
circle is
​

Answer 1

Answer:

Length of diameter is 4.

Step-by-step explanation:

Let the other end be (x,y) , now as origin is the center , so it will be the midpoint of the points (x,y) and (-2,10)

Therefore x=2

y=10

Now applying distance formula between the points (-2,10)and (2,10)

d=√16

d=4

The length of diameter of the circle is 4.
