How do you change 7 pie radians into degrees?
The formula for converting radians to degrees is the given angle in radians multiplied by (180 degrees / pi), so in this case, 7 pi radians would be equal to 1260 degrees. (By the way, the greek letter pi isn't spelled with an e).
What is the total interior angles of a 9-gon?
The answer is 7pi radians, or 7*180° = 1260° (N-2)pi radians, or (N-2)*180° N is the number of sides on the polygon; Sum of interior angles formula
What is sin A equals 7 over 25?
It is a trigonometric equation. A = sin-1(7/25) = 0.284 radians.
Does pie equal to 22 over 7?
No, 22 over 7 is not equal to pi, but is instead an approximation of pi, as it only gives you 3 digits of pi, the rest (after 3.14) in 22/7 are wrong. Pi is 3.141926......... And goes on forever, meaning that a fraction such as 22/7 will never be fully equivalent to pi.
How do calculate sin of 20?
The easiest way to find the value of sin(20) is to use a scientific calculator or a computer. But if you want to actually calculate it, you could try the following. First you need to make sure that the angle is expressed in radians. 180 degrees = pi radians so 20 degrees =20*pi/180 = pi/9 radians. Call this value x. Then find x/1! - x3/3! + x5/5! - x7/7! + ... The further you go, the more accurate your result.
