In the given figure, the shape of the top of a table is that of a sector of a circle with centre O and `/_AOB=90^(@)`. If `AO=OB=42cm` then find the perimeter of the top of the table.

Text Solution

Verified by Experts

The correct Answer is:
`282cm`
Required perimeter `=` (circumference `-` arc AB) `+ (OA+OB)`
`={(2xx22/7xx42)-(2xx22/7xx42xx90/360)+(42+42)}cm`
`=(264-66+83)cm=282cm`
