Take one sector that includes the shaded segment:-
There are 6 sectors altogether and the angle at center = 369 / 6 = 60 degrees.
The sides of the triangles ar equal to radius of the circle = 9 units.
Area of this sector = pi r^2 * 60 /360
= pi * 9^2 / 6 = 42.412 units^2
Area of the triangle = 1/2 * 9^2 * sin 60 = 35.074 units^2
So the area of the shaded segment = 42.412 - 35.074 = 7.338 unIt^2
AS there are 4 shaded segments the answer is 4 *7.338 = 29.3 units^2
Answer:
Step-by-step explanation:
- Total distance = 10 miles
- Total time = 2 hours
- Distance walked = x
- Speed walked = 2 mph
- Distance cycled = 10 - x
- Speed cycled = 15 mph
<u>Using the given data we can have the equation below to the time:</u>
- x/2 + (10 - x)/15 = 2
- 30x/2 + 30(10 - x)/15 = 30(2)
- 15x + 20 - 2x = 60
- 13x = 60 - 20
- 13x = 40
- x = 40/13
- x = 3.08 miles <em>rounded to 2 decimal places</em>
Answer:
(1/2, -1/2)
Step-by-step explanation:
The center of the circumcircle is the midpoint of the hypotenuse of the inscribed right triangle, so is the midpoint of UW.
(U+W)/2 = ((-3, 2) + (4, -3))/2 = (1, -1)/2 = (1/2, -1/2) . . . . center
_____
If you mean something else, we need a better description. There are an infinite number of points on the circumference of the circle, none of which is listed here.
