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
