we know that circumference = 2π r
=> 2π r = 22
=> r = 11/π
area of circle = πr²
= π × 11/π × 11/π
= 121/π
Therefore area of a quadrant will be
1/4 × 121/π
or 121×7/22×4
= 9.625 cm²
=> 2π r = 22
=> r = 11/π
area of circle = πr²
= π × 11/π × 11/π
= 121/π
Therefore area of a quadrant will be
1/4 × 121/π
or 121×7/22×4
= 9.625 cm²
