16b^6 sqrt 6a would be the answer
To look for the area of a sector of a circle, the following formula is used:
Area = ( n / 360 ) * pi * r^2
Where: n = measure of arc in degrees
pi = 3.1416
r = radius
Since we are already given all of the needed parts of the formula, direct substitution is done, as shown below:
Area = ( n / 360 <span>) * pi * r^2
</span>Area = ( 45 / 360 ) *3.1416 * (8)^2
Area = 25.133 in^2
Therefore, the area of the sector of the circle is 25.133 sq. in.
Answer:
y = 4x
Step-by-step explanation:
Points on the graph:
- (-4, -16), (0,0), (4, 16)
<u>Slope intercept form:</u>
<u>Working out slope using two of the points:</u>
- m= (y2-y1)/(x2-x1)
- m= (0- (-16))/(0- (-4))
- m= 16/4
- m= 4
<u>The equation is now:</u>
<u>Using one of the points to find b:</u>
- -16 = 4*(-4) +b
- -16 = -16 + b
- b = 0
<u>So the final form is:</u>
<u>Correct answer choice is</u> the last one
