Question

I am not sure on how to do this ​

Answer 1

8.

Explanation:

Use the intersected chords of a circle theorem:

AP * PB = CP * PD

12 * 4 = CP * 6

6CP = 48

CP = 8.

Answer 2

CP = 8 cm

Explanation:

Given two chords that intersect inside a circle, then then the product of the parts of one chord is equal to the product of the parts of the other chord, that is

DP × CP = AP × PB ← substitute values

6 × CP = 12 × 4

6CP = 48 ( divide both sides by 6 )

CP = 8
