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.
the same as pi squared, which is 9.86960440109
19.7392088 is also = to pi for instince infinaty=pi = never tnding so the formlea infinity=pi.
Pi, is an irrational number (it cannot be written as a fraction) For this reason, 3 times pi is also irrational.
The volume of a sphere is given by the formula V = (4 pi r3)/3 3V = 4 pi r3 3V/4 pi = r3 (3V/4 pi)1/3 = r [3(250)/4 pi]1/3 = r (750/4 pi)1/3 = r 8.383 ≈ r
Yes
(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.
About 20.29791
The angle can be 0, pi/2, pi, 3*pi/2 or 2*pi radians.

Pi plus 86 equals 89.14
3.14626437 (Pi)
If I understand the question correctly, the answer is plus or minus 3*sqrt(pi)/pi = -1.69 and 1.69 (rounded to two decimal places).

The formula for volume is 1/3 Bh ( 1/3 pi times radius squared times the height.) The formula for surface area is 2 pi r h plus 2 pi r squared.
pi+pi is 6.28. all that you have to do is add up the numbers.-fromama fromamzez.webs.com
