Answer:
15.1
Step-by-step explanation:
We know that the area of the circle is
, but we are looking for the portion of the circle, this means we multiply it by the portion of the circle that is shaded.
Area of shaded region = 
where r = 4 and x = 108, the 360 comes from the fact that the total degrees around the circle is 360, so dividing the total amount of degrees by the angle will give us the portion we are looking for.
Area of shaded region =
= 15.1
Another way to think about it is that the area of the total circle is
, multiplying it by a fraction, a number less than 1, would give us a smaller value.
Hope this helps.
The question is basically asking you how much area of the yard the pool takes up, in essence the area the pool takes up.
So we are going to find the area of the pool.
Area of pool is = pi x r^
= 3.14 x 7^2
= 153.86 ft^2
Therefore the pool takes up 153.86 ft^2 of space.
Do you know how to write that equation at the start that is
f(S) = {s
Answer:
509.35 feet
Step-by-step explanation:
16°23' means 16 degrees and 23 minutes. A minute is 1/60 of a degree.
16°23' = 16 + (23/60) = 16.383°
Similarly:
49°29' = 49 + (29/60) = 49.483°
When the boat is first noticed:
tan(16.383°) = 200 / a
a = 200 / tan(16.383°)
a = 680.27
When the boat stops:
tan(49.483°) = 200 / b
b = 200 / tan(49.483°)
b = 170.92
So the difference is:
a − b = 680.27 − 170.92 = 509.35
The boat traveled 509.35 feet from the time it was first noticed to the time it stopped.
