Question

C is centere of the circle whose raidus is 10cm find the distance of the chord from the centre if the lenght of the chord is 12cm
​

Answer 1

Answer:

8cm

Step-by-step explanation:

Given,

• Radius,r of the circle = 10cm
• Length of the chord,c = 12cm

To find,

• distance from center to chord, height = ?

We know,

• we can find the distance using Pythagorean formula.
• The radius is the hypotenuse ac = 10cm,chord/2 is the base bc = 12/2 = 6cm and height ab = ?

Pythagorean formula :-

• ac² = ab² + bc²

Substitute the values in the formula :-

• 10² = ab² + 6²
• ab² = 10² - 6²
• ab² = 100 - 36
• ab² = 64
• ab = √64
• ab = 8cm

Hence,

The distance from center to chord is 8cm
