Answer:
16 cm
Step-by-step explanation:
We have to first find the radius of the circle.
The area of a sector is given as:
where α = central angle of the sector = 120°
r = radius of the circle
Therefore:
The diameter of a circle is twice its radius, therefore:
D = 2 * 8 = 16 cm
The diameter of the circle is 16 cm
Answer:
<em>17 miles</em>
Step-by-step explanation:
If Heidi starts out by traveling 15 miles south, then y = -15 miles
If she then turns and rides 8 miles east, then x = +8miles
The distance from her starting position to her tent is gotten using the pythagoras theorem as shown;
d = √(-15)²+8²
d = √225+64
d = √289
d = 17miles
<em>Hence her distance from her starting position to her tent is 17 miles</em>
Answer:
no
Step-by-step explanation:
x+y=6
Substitute the point into the equation and see if it is true
0 + -2 = 6
-2 =6
This is not true so the point is not a solution
