Rohan draws a circle of radius 10 cm with the help of compass and scale. He also draws two chords, AB and CD in such a way that
AB and CD are 6 cm and 8 cm from the centre O. Now, he has some doubts that are given below. Help him out by answering these questions:
1 answer:
It can be deduced that the chord of AB will be 16 cm and the chord of CD will be 12 cm.
<h3>How to calculate the chord</h3>
From the information given, we will use Pythagoras theorem to find half of AB. This will be:
= ✓10² - ✓6²
= ✓64
= 8.
Therefore, AB = 8 × 2 = 16cm
The length of CD will be:
= 10² - ✓8²
= ✓36
= 6
The length of CD = 6 × 2 = 12cm.
