The area of the shaded region:
A = r ² π - a²
where: r = d/2 = 7√2 / 2
A = ( 7√2 / 2 )² · 22/7 - 7²
A = 49 · 2 / 4 · 22/7 - 49
A = 49/2 · 22/7 - 49
A = 7 · 11 - 49
A = 77 - 49
Answer: A (shaded) = 28
125 x 12 = 1500
1500 + 50 = 1550
1550 - 700 = 850
You would need $850
A square root can’t be a negative value, so the root would be greater than or equal to zero.
Range:
Y>=O
[O, infinity)
Answer:
x = 50°
y = 130°
z = 130°
Step-by-step explanation:
the central angle is equal to it's arc in degrees.
y = 180° - 50° = 130°
