Compute the radius of the largest circle that is internally tangent to the ellipse at $(3,0),$ and intersects the ellipse only a
Artyom0805 [142]

Answer: radius of the largest circle is Zero.

Step-by-step explanation: A circle can't fit into an ellipse with such coordinate (3,0). What that coordinate means is that the ellipse lies along the x axis 3unit from the origin along the x axis and 0 unit from the origin along the y axis. At which no circle can fit in.

Moreso, the the coordinates at which the circle intercepts the ellipse as to be uniform not (3,0).

A circle as a constant radii coordinate on both axis.

I believe you can now see why my answer is Zero.

In circle Q with
jonny [76]

Answer:

The minor arc PR is 42 degrees

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The inscribed angle is half that of the arc comprising

so

m\angle PSR=\frac{1}{2}(arc\ PR)

we have

m\angle PSR=21^o

substitute

21^o=\frac{1}{2}(arc\ PR)

arc\ PR=21(2)=42^o

Remember that the minor arc in a circle is less than 180 degrees

therefore

The minor arc PR is 42 degrees
