Answer: third option.

Step-by-step explanation:

A tangent of a circle is defined as a line that touches that circle in exactly one point.

You can observe in the figure attached that:

The segment MN and the segment ST are not the tangent of the given circle, because this segments intersect it in two points.

The segment RO is the radius of the circle.

The segment PQ touches the circle in one point.

Therefore, the segment PQ is the tangent of the circle.

The circles are identical. What is the circumference of each circle? Circle 1: radius of 2x; Circle 2: diameter of 2x+3. A. 3/2

Delicious77 [7]

Answer:

C=6π

Step-by-step explanation:

It is given that, two circles are identical. The radius of first circle is 2x and the diameter of other circle is 2x+3.

If identical, it means that the radius of both circles are same i.e.

$2x=\dfrac{2x+3}{2}\ \ (\because\ r=\dfrac{D}{2}, d=\text{diameter})\\\\4x=2x+3\\\\2x=3\\\\x=1.5$

Radius of both circles is 2(1.5)=3

The circumference of a circle is given by :

$C=2\pi r\\\\C=2\pi (3)\\\\C=6\pi$

So, the circumference of each circle is 6π.
