Step-by-step explanation:
angle of circle=360° area of circle 22/7 r^2 area of sector= 0/360 x 22/7r^2(here 0=angle subtended) 6/360°=60° so, 60°/360 x 22/7 x^2 1/6 x 3.14x(7.5)^2=176.625 cm^2

r = 7.5
it has 6 equal parts
θ = 360/6 = 60°
converting the ° into radian
radian = 60 × π/180
= π/3
Area of sector = 1/2 r² θ
= 1/2 × (7.5)² × π/3
= 56.25π /6
= 9.375π
= 9.375 × 3.14 applying value of π
= 29.4375 cm²
The area of each sector = 29.4375cm²
