What angle is Sine and cosine equal?
at a 45 degree angle, or pi/4
How do you find the area of three quarters of a circle?
You find the area using Pi x radius squared then multiply that by 3/4.
How do you find cosine squared at 30 degrees?
cos(30) = sqrt(3)/2 so cosine squared is 3/4.
What is 81 divided by pi?
25.7831 (to 4 dp)
What is the volume of a sphere with diameter 3m?
~14.1372 V=(4/3)pi r^3 V=(4/3)pi (1.5)^3=(4/3)pi 3.375=4.5pi~14.1372
What is pi times 3 divided by 4?
12
What is the volume of the sphere with a radius of 12?
Volume is 4/3 x "pi" x r3 or 4(pi)r3 divided by 3. Volume=7234.56 when pi is 3.14
What angle is Sine and cosine equal?
at a 45 degree angle, or pi/4
How would you prove that the surface area of a sphere when divided by its volume is always equal to 3 over its radius giving examples?
Area = 4*pi*radius2 and volume = 4/3*pi*radius3 And: 4*pi*r*r divided by 4/3*pi*r*r*r => 3*4*pi*r*r/4*pi*r*r*r Then by cancelling it becomes: 3/r Check: If radius is 6 then it is 3/6 or 1/2 Check: If radius is 0.5 then it is 3/0.5 or 6 Check: If radius is 11 then it is 3/11
What is 4 times pi times pi times 4 divided by 2?
4 times pi times 4 divided by 2 is 78.9568352087
What is sine of 3 pie divided by 4?
0.75
What set of numbers does not include pi divided by pi?
Any set that does not contain the number 1. For example, even integers, multiples of 3, or 4, or 5, ... (0, 1) {1/2, 2/3, 3/4, 4/5, ...} {pi, pi2, pi3, ... }
How do you find the radius of a sphere whose volume is 32 times pi divided by 3?
96
What is pi divided by 4?
45 degrees or 0.785398163. The first part is pi radians divided by 4, not quite the same thing.
What is the square root of pi multiplied by 4 and divided by 12?
0.3333
How many balls each of radius 1 cm can be made from a solid sphere of lead of radius 8 cm?
It is: (4//3*pi*83) divided by (4/3*pi*13) = 512
How do you find the area of three quarters of a circle?
You find the area using Pi x radius squared then multiply that by 3/4.
