Answer:
Area of segment = 9.8 cm² (Approx.)
Step-by-step explanation:
Given:
Angle θ = 120°
Radius of circle = 4 cm
Find:
Area of segment
Computation:
Area of segment = [θ/360][π][r]² - [1/2][r²][sinθ]
Area of segment = [120/360][3.14][4]² - [1/2][4²][sin120]
Area of segment = [0.333][3.14][16] - [0.5][16][0.866]
Area of segment = 16.7299 - 6.28
Area of segment = 9.8019
Area of segment = 9.8 cm² (Approx.)
Answer:
No
4x squared + 8x + 3 =
4x squared: 16x
16x + 8x + 3
add 16 and 8 = 24x + 3 and that's your answer
Concentric circles because if a line is tangent to one circle, it would only intersect teh other
Dy/dx = -y inx iny
(y in x in y) dx + dy = 0
(y in x in y ) dx = - dy
(in x )dx = - (1/ y in y) dy
you just need to integrate both sides
Hope this helps
