Question

In a circle of radius 17cm calculate the length of a chord which is 8cm from the centre​

Answer 1

The length of the chord is 30cm

Explanation:

Given

`r = 17cm`

`d = 8cm`

Required

Calculate the chord length (L)

This is calculated as:

`L = 2 * \sqrt{(r^2 -d^2)`

So:

`L = 2 * \sqrt{(17^2 - 8^2)`

`L = 2 * \sqrt{225`

`L = 2 * 15`

`L = 30cm`
