What quadrant is 28pi divided by 3 in?
9.3333
Why is cosine negative in the third quadrant?
On a Unit Circle, the cosine is the x coordinate of the point on the circle represented by an angle. Angles greater than 90° (pi/2 radians) and less than 270° (3*pi/2 radians) are to the left of the y-axis, so x is negative. Quadrant I is the upper right quadrant (x positive, y positive) 0° < ɵ < 90° Quadrant II is the upper left quadrant (x negative, y positive) 90° < ɵ < 180° Quadrant III is the lower left quadrant (x negative, y negative) 180° < ɵ < 270° Quadrant IV is the lower right quadrant (x positive, y negative) 270° < ɵ < 360°
What is the area of a quadrant 12 in. using 3.14 for pi?
Assuming that 12 in refers to the radius, then the area is 113.04 square inches.
What is the exact value of the expression cos 7pi over 12 cos pi over 6 -sin 7pi over 12 sin pi over 6?
cos(a)cos(b)-sin(a)sin(b)=cos(a+b) a=7pi/12 and b=pi/6 a+b = 7pi/12 + pi/6 = 7pi/12 + 2pi/12 = 9pi/12 We want to find cos(9pi/12) cos(9pi/12) = cos(3pi/4) cos(3pi/4)= cos(pi-pi/4) cos(pi)cos(pi/4)-sin(pi)sin(pi/4) cos(pi)=-1 sin(pi)=0 cos(pi/4) = √2/2 sin(pi/4) =√2/2 cos(pi)cos(pi/4)-sin(pi)sin(pi/4) = - cos(pi/4) = -√2/2
Pi is known to be over how many digits long?
Pi is infinite. The current number of digits calculated is over ten-trillion. If you want to find a pretty good estimate, divide 22 by 7.
What quadrant would pi over 5 be in?
Pi / 5 would be in Quadrant I.
What quadrant would 7 pi over 5 be in?
7*pi/5 = 1.4*pi pi < 1.4*pi < 1.5*pi and so the angle is in the third quadrant.
How you find the perimeter of quadrant?
If you the radius of the circle is r then the perimeter of a quadrant = r*(2 + pi/2).
How do you find area of a quadrant circle?
If the radius of the circle is r, then the area of the quadrant is 0.25*pi*r^2
Is pi a quadrant?
No, it is not.
Is pi quadrant?
No
Formula to find circumference of quadrant?
Circumference of a circle = 2 * pi * r pi = 3.1415926535897932384626433832795 r= radius of circle Hence Circumference of a Quadrant = 2 * pi * r / 4 = pi * r / 2 = 0.5 * pi * r For more accurate value of pi, please refer: http://en.wikipedia.org/wiki/Pi
What is sin of 3 pi over 2?
sin pi/2 =1 sin 3 pi/2 is negative 1 ( it is in 3rd quadrant where sin is negative
Formula to find the area of a quadrant?
(radius x radius x pi) divided by 4
What is the quadrant of 8.3?
8.3 Radians? is in the second quadrant. 8.3/pi*180 is about 115. 115 is in the second quadrant.
What is formula of perimeter of quadrant?
In a circle of radius, r, perimeter of quadrant = pi*r/2 + 2r = r*(pi/2 + 2)
How do you find the perimeter of quadrant?
If you the radius of the circle is r then the perimeter of a quadrant = r*(2 + pi/2).
