The equation of the circle is may be expressed as,
(x - h)² + (y - k)² = r²
where h and k are the abscissa and ordinates of its center, respectively, and r is radius. Substituting the given values to the equation above,
(x - 5)² + (y - 3)² = 4²
Simplifying further the equation gives,
x² + y² - 10x - 6y + 18
We need the radius to find the area of sector.
radius = 20/2 = 10
Area of sector:
πr²(x/360) = x is the central angle in degrees.
π(10)²(36/360)
10π in²
Hope this helps :)
Answer:
Step-by-step explanation:
Slope is (80,20)(120,30) is A 1/4
(80,20) 20 is 1/4 of 80
(120,30) 30 is 1/4 of 120
1 represent the number of apples at the start.
Answer:
AB=12 BC=9
Step-by-step explanation:
Any side of a triangle must be shorter than the other two sides added together.
AB and A'B' must measure LESS than the other 2 sides
15 is 3/4 of 20
12 is 3/4 0f 9
20/15 12/9 = 1.3333333........
