Step-by-step explanation:
radius of circle = 2 cm
area of circle = πr²
= 22/7 × 2 × 2
= 88/7
= 12.57 cm²
circle is divided into four equal sector
each sector area will be = area of circle/4
= 12.57/4
= 3.14 cm²
other method
area of sector = x⁰/360 × π r²
circle is divided into four equal sector therefore the angle subtended at centre = 360/4 = 90⁰
= 90/360 × 22/7 × 2 × 2
= 1/4 × 88/7
= 22/7
= 3.14 cm²
Hope you get your answer
