As stated the area of the circle is 85π ft2. The area of the sector BAC is a portion of this full circle area. the sector is made of 2 radii and arc that has rotated by 36°.
the magnitude of the central angle in the circle is 360°
Area for 360° central angle - 85π ft2
then the area for 1° = 85π ft2/360°
the area of 36° sector = 85π ft2/360° x 36°
= 8.5π ft2
The answer is 8and 10 when you divided is 0.8
Answer:
0.81
Step-by-step explanation:
Answer:
<u>x = 36</u>
Here's how I got that:
<em> - Group like terms -</em>
x - 2 + 2x + 4 + 2x - 2 = 180
↓
5x - 2 + 4 - 2 = 180
↓
5x = 180
<em> - Divide both sides by 5 - </em>
<em> </em> 5x/5 = 180/5
↓
<em> </em><u><em>x </em></u><u>= 36</u>
<em>~ That's all folks ~</em>

Answer:
1 and 2 answers are correct
Step-by-step explanation:
2x-y= -8
x-y = -4
ADD BOTH (y is cancelled)
3x= -12
x= -4
-8+y=-8
y=0
-4-y = -4
Multiply all by -1
4+y=4
y=0
