Answer:
Area = 95.4 cm²
Step-by-step explanation:
Given
θ = 135°
r = 9cm
Required
Calculate the area of the sector
Area of a sector is:
Area = θ/360 * πr²
Substitute values for θ and r
Area = 135/360 * π * 9²
Area = 0.375 * π * 81
Take π as 3.14
Area = 0.375 * 3.14 * 81
Are = 95.3775
Area = 95.4cm² ---- approximated
