Answer:
The diameter of the circle is 10 cm.
Step-by-step explanation:
As
The arc length formula is given by:
where
First lets find r,
∵ s = 6 cm and = 1.2 radians
As
so
cm
Therefore, the diameter of the circle is 10 cm.
Answer:
Its 10 cm

Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given that
Coordinates of B = (4,-3)
Coordinates of C = (-4,3)
We need to find the collinear point with B and C.
There is one method to find the collinear point i.e. Slope method.
Slope of BX = Slope of CX =
Let Coordinates of X = (0,0)
So, Slope of BX is given by
Slope of CX is given by
So, Slope of BX = Slope of CX =
And we can see from the graph (0,0) is the collinear point with B and C too.
Hence, Option 'A' is correct.
