Answer 2

Answer:

the distance between the centre and the chord is 7cm

Step-by-step explanation:

First, sketch it.

You find a right-angle triangle with hypotenuse 25 (the radius) and one side 7 (the altitude) and the unknown 3rd side

Pythagoras:

7² + x² = 25²

x² = 625 - 49 =576

x = 24

The chord is 48cm

(You may recognise the 7–24–25 Pythagorean Triplet, like 3–4–5 and 5–12–13)
