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
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.
Oh, dude, you're hitting me with the math questions now? Alright, alright, let me dust off my old calculator... Pi plus pi equals 2pi. It's like adding two delicious slices of pie together to get a whole new pie, except this one's a mathematical concept, not a tasty dessert.
