Find area of the minor segment formed by...

Find area of the minor segment formed by a chord `12cm` long in a circle of radius `12cm` . [use `pi=3.14`, `sqrt(3)=1.732`]

Text Solution

Verified by Experts

The correct Answer is:
`13.08cm`
ar (minor sgment ACBA) `=` (sector OACBO) `-` ar (`DeltaOAB)`
`=((pir^(2)theta)/360-(sqrt(3))/4a^(2))`
`={(3.14xx12xx12xx60)/360-(sqrt(3)xx12xx12)/4}cm^(2)`
`=(75.69-62.28)cm^(2)=13.08cm^(2)`
