Let

k_{1}

and

k_{2}

be circles with the centres

S_{1}

,

S_{2}

, and the radii of lengths

5 cm

and

1 cm

consecutively. Given

| S_{1} S_{2} | = 7 cm

, what is the mutual position of these circles?

The circle

k_{2}

lies outside the circle

k_{1}

.

The circle

k_{2}

lies inside the circle

k_{1}

.

The circles

k_{1}

and

k_{2}

intersect.

The circles

k_{1}

and

k_{2}

are externally tangent.

The circles

k_{1}

and

k_{2}

are internally tangent.
