If you are meaning it in sense of a geometry, the it's 3 * 180 degrees (which is what they mean by pi) = 540 degrees.
Circumference: 2*pi*3 = 6*pi inches Area: pi*3 squared = 9*pi square inches
The formula for the volume of a square is: A = 4/3 * pi * r3 Therefore A = 4/3 * pi * 33 = 4/3 * pi * 27 = 36 * pi = approx 113.10 m3
The circumference C is pi times the diameter of the circle, which is twice the radiusC= pi *2rThe area A is pi times the radius squaredA = pi r2where pi = about 3.14159Example:For a radius of a 3 cmC = pi x (3 x 2) = pi x 6 = about 18.85 cmA = pi x (3)2 = pi x 9 = about 28.275 cm2
Volume of sphere = 4/3*pi*r3 So volume of half a sphere = 2/3*pi*r3= 2/3*pi*103 = 2000*pi/3 = 2094.4 cubic units
V=4/3 X pi X r3Since you have the volume formula, I don't understand why you're having difficulty.volume = (4/3) * pi * r*r*rvolume = (4/3) * pi * 125volume = (500*pi)/3volume = 523.59877559833Thus, the volume of the sphere is approximately523.6 cubic centimeters.volume = (4/3) * pi * r^3 and since we know that r=5volume = (4/3) * pi * 5*5*5approximating "pi" as 3.14159265359volume = (500*3.14159265359)/3

[pi^(1/3)]^2 * pi = pi^(2/3) * pi = pi^(5/3) The answer is the cubic root of pi to the fifth power.
18pi m^3 ~ 56.5486678 m^3 sphere: (4/3)pi(r^3) hemisphere: ((4/3)pi(r^3))/2=(4/6)pi(r^2)=(2/3)pi(r^3) d=6 r=3 (2/3)pi(3^3)=(2/3)pi(27)=(54/3)pi=18pi
(pi + pi + pi) = 3 pi = roughly 9.4248 (rounded) Well, if you use the common shortened version of pi which is 3.14 and add that 3 times, you get 9.42.
Volume of a sphere = 4/3 pi R3V = (4/3) (pi) (2)3 = 8/3 pi = 8.3776(rounded)

11pi/12 = pi - pi/12 cos(11pi/12) = cos(pi - pi/12) cos(a-b) = cos(a)cos(b)+sin(a)sin(b) cos(pi -pi/12) = cos(pi)cos(pi/12) + sin(pi)sin(pi/12) sin(pi)=0 cos(pi)=-1 Therefore, cos(pi -pi/12) = -cos(pi/12) pi/12=pi/3 -pi/4 cos(pi/12) = cos(pi/3 - pi/4) = cos(pi/3)cos(pi/4)+sin(pi/3) sin(pi/4) cos(pi/3)=1/2 sin(pi/3)=sqrt(3)/2 cos(pi/4)= sqrt(2)/2 sin(pi/4) = sqrt(2)/2 cos(pi/3)cos(pi/4)+sin(pi/3) sin(pi/4) = (1/2)(sqrt(2)/2 ) + (sqrt(3)/2)( sqrt(2)/2) = sqrt(2)/4 + sqrt(6) /4 = [sqrt(2)+sqrt(6)] /4 Therefore, cos(pi/12) = (sqrt(2)+sqrt(6))/4 -cos(pi/12) = -(sqrt(2)+sqrt(6))/4 cos(11pi/12) = -(sqrt(2)+sqrt(6))/4
Yes

No, for example if A = Pi/3. Then sin3A = sin pi = 0, but sinA = sin Pi/3 = 1/2. So for A = Pi/3, the sum is 1/2, not zero. It can't be proved because the statement is false. For example if A = Pi/3. Then sin3A = sin pi = 0, but sinA = sin Pi/3 = 1/2. So for A = Pi/3, the sum is 1/2, not zero.

Volume is not necessarily in pi. For example, the volume of a cube, with sides of 3 cm is 3*3*3 = 27 cubic cm. Not a hint of pi anywhere in that!
