Equation of the circle is (x + 5)² + (y - 5)² = 9
Step-by-step explanation:
Equation is (x - -5)² + (y - 5)² = 3²
⇒ (x + 5)² + (y - 5)² = 9
Answer:
(x + 5)² + (y - 5)² = 9
Radius = 504units
Angle = 10°
Length of arc = 28π units
L = ∅/360 × 2πr
28π = 10/360 × 2πr
28π = 1/36 × 2πr
2πr = 28π × 36
π cancelled off.......
2r = 28 × 36
r = (28 × 36)/2
r = 28 × 18
r = 504units
x=12
7+x=2x-5
12=1x
First add 11 then -69
