The area of a sector is 339.336 cm²
The area of a sector is defined to be as the region of space bounded by a boundary from the center of the circle.
It can be determined by using the formula:
Given that;
- Radius r = 18 cm
- Angle θ = 120°
Then. the area of the sector can be calculated as:
A = 339.336 cm²

Answer: (4,-5)
Step-by-step explanation:
8y = -40
(divide by 8)
y = -5
(plug it in to one of the equations)
3x + 6*-5 = -18
3x + -30 = -18
3x = 12
x = 4
Yes because it can be expressed as a fraction (9/27)

17.
the triangle of sides ‘l’ and ‘l-h’ is a right angled triangle.
Then
Then
Then
18.
For l = 6 and θ = 40 :
= 6-6cos(40)
= 1.403733341286
