Answer:
area of the sector = 360π cm²
Step-by-step explanation:
To calculate the area of the sector, we will follow the steps below;
First write down the formula for calculating the area of a sector.
If angle Ф is measured in degree, then
area of sector = Ф/360 × πr²
but if angle Ф is measured in radians, then
area of sector = 1/2 × r² × Ф
In this case the angle is measured in radiance, hence we will use the second formula
From the question given, radius = 15 cm and angle Ф = 8π/5
area of sector = 1/2 × r² × Ф
=1/2 × 15² × 8π/5
=1/2 ×225 × 8π/5
=360π cm²
area of the sector = 360π cm²

Answer:
1. (-3 , 3) (-8 , 8)
2. (3 , -3) (8 , -8)
3. (0 , 0) (5 , 5)
Step-by-step explanation:
1. Multiply the X values by negative 1 to reflect across the X axis.
2 Multiply the Y values by negative 1 to reflect across the Y axis.
3. Subtract 3 from each value when everything is getting moved towards a lower number.
