Sector area = 0.5 * r^2 * angle (in radians)
so:
16 pi = 0.5 * r^2 * (90*pi/180)
r^2 = 16 pi /(0.25 pi) = 64
r = 8
therefore it would be d
Idk if this will help but here. Thirty six divided by four equals nine.
It will hit the ground after 3.499 seconds.
To solve this you first have to find the value of h(0) in this equation. That is the height from which it was dropped.
You can input any of the points into the equation and solve for the missing part. You will get 60 for the height.
The use the quadratic formula to see that it reaches the ground after 3.499 seconds.
Average rate=delta y/delta x...
c=(72-48-8+16)/(6-2)
c=32/4
c=8
Using the definition of vertical angles, the value of z is: 15.
<h3>Vertical Angles Pair</h3>
The two pairs of opposite angles formed when two straight lines intersect are called vertical angles, and are therefore congruent to each other.
Thus:
2z + 10 = 40
2z = 40 - 10
2z = 30
z = 30/2
z = 15
Therefore, using the definition of vertical angles, the value of z is: 15.
