Step-by-step explanation:
It was kinda tuff but i managed
Okkaay so this would be 3.14 x (5x5) x 9 = <span>706.5
V=</span>πr2h
Answer:
1) 270 degrees
2) pi/4 rad
Step-by-step explanation:
1.) For which value of theta is sine theta = negative 1?
Given
sintheta = -1
theta = arcsin(-1)
theta = -90degrees
Since sin is negative in the third and 4th quadrant
In the third quadrant, theta = 180 + 90 = 270degrees
In the fourth quadrant, theta = 360 - 90 = 270 degrees
Hence the required value of theta is 270degrees
2) Given the radius of the circle to be 1, the y axis value will also be 1 units
Opposite = 1
adjacent = 1
hyp = √1²+1²
hyp = √2
sin theta = opp/hyp
sin theta = 1/√2
theta = arccsin(1/√2)
theta = 45 degrees
Express in radians
45 degrees = pi/4 radians
Hence the required angle in the first quadrant is pi/4 rad
Answer: The range of the given data is $120.
Step-by-step explanation:
For a set of observations, we know that the range of the set is given by:-
In the given data , the largest data value= $212
The smallest value= $92
Therefore, the range of the given observations is given by:-
Hence, the range of the given data is $120.
