What is the circumference and area of a circle with a radius of 3 inches?
Circumference: 2*pi*3 = 6*pi inches Area: pi*3 squared = 9*pi square inches
What is the volume of a sphere of radius 3 meters?
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
How do you find the circumference and area of a circle from the radius?
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
What is the volume of a half sphere with a radius of 10?
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
What is the volume of a sphere with a radius of 5 cm?
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
What is pi times 3 divided by 3?
9
What is the cubic root of pi squared multiplied by pi?
[pi^(1/3)]^2 * pi = pi^(2/3) * pi = pi^(5/3) The answer is the cubic root of pi to the fifth power.
What is the volume of a hemisphere with a diameter of 6 meters?
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
What is pi plus pi plus pi?
(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.
What is the volume of a sphere with a radius of 2 without the pi?
Volume of a sphere = 4/3 pi R3V = (4/3) (pi) (2)3 = 8/3 pi = 8.3776(rounded)
3 plus pi equals pi plus 3?
Yes
Is the volume formula universal for all the figures?
No, the volume formula is not universal for all figures. Different shapes and objects have different formulas to calculate their volume based on their unique dimensions and properties. Each shape requires its own specific formula to accurately determine its volume.
What is the exact value using a sum or difference formula of the expression cos 11pi over 12?
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
What is the circumference and area of a circle with a radius of 3 inches?
Circumference: 2*pi*3 = 6*pi inches Area: pi*3 squared = 9*pi square inches
Is sin3A plus sinA equal to 0?
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.
