Area of circle = pi r^2 = 81pi
1/3 of circle = 81pi / 3 = 27 pi units^2
answer
B. 27 pi units^2
The relationship of the angles to the sides opposite those angles is always:
30°=1, 60°=√3, and 90°=2
So the longer leg can be found using the ratios from above...
L/S=√3/1 and we are told that the shorter side is 5 in so
L/5=√3
L=5√3
So A. is the correct answer.

Answer:
the volume of the sphere will be 4 times the volume of the cone;
Step-by-step explanation:
<u>The question is on volume comparison</u>
Volume of a sphere=4/3 
×r³
Volume of a cone= /3×r²h
where r is the radius and h is the height
<u>Apply the condition</u>
If r=h=1 unit
Then volume of sphere will be= 4/3 × ×1³ = 4/3
And volume of the cone will be= /3 ×1²×1 =/3
We can see the volume of the sphere will be 4 times the volume of the cone;
4/3 = 4×/3
Answer:
30(-2) = -60
Step-by-step explanation:
The change in speed from a higher location to a lower location is 2 m/s, v = -2 m/s (from higher to lower)
We need to find the equation that models the change in the bird's position at 30 seconds.
Distance = speed × time
change in position = (-2) × 30
= -60
Hence, the correct option is (B).
