Answer:
Approximately
.
Step-by-step explanation:
Convert the angle of this sector to radians:
.
The formula
relates the arc length
of a sector of angle
(in radians) to the radius
of this sector.
In this question, it is given that the arc length of this sector is
. It was found that
radians. Rearrange the equation
to find the radius
of this sector:
.
The perimeter of this sector would be:
.
Yes because
Kate: 3X2 = 6
Jake: 3X2 = 6
Emily: 3X2 = 6
add all of those together and you get 18
1 unit to the left
Check the table I attached
will she would have rode 4 3/5 miles in all.
2 3/10+2 3/10=4 3/5
that is 2 3/10 there and 2 3/10 back so you would add that together.
MILES IN ALL 4 3/5
Hope this helps
A = pi * r^2
<span>A = 3.14 * 50^2 </span>
<span>A = 7,850 square miles (area of the 50 mile broadcast signal)
A = pi * r^2
A = 3.14 * 75^2
A = </span>17,662.5 = 17,663 square miles (area of the 75 mile relayed signal)
Now we just need to subtract the 50 mile signal from the 75 mile signal, so:
17,663 - 7,850 = <span>9,813 square miles greater
Hope this helps :)
