Answer:
A = 27π cm²
Step-by-step explanation:
the area (A) of the sector is calculated as
A = area of circle × fraction of circle
the central angle of the shaded sector = 360° - 90° = 270° , then
A = πr² × 
= π × 6² × 
= 36π ×
= 9π × 3
= 27π cm²

Answer:
16/9
Step-by-step explanation:
We can find the slope given two points by using the following formula
