Step-by-step explanation:
area of circle : πr²
area of sector : x/360 x πr²
firstly, you have to find. the area of a circle
π(6)² = 36π
then, find the area of the of the sector (not in the shape)
90°/360° x π(6)² = 12π
[90° is given)]
next, you just minus the total and the area of the sector.
36(3.14) - 12(3.14) = 75.36 units
