Oct 6, 2023 · To convert 4π from radians to degrees, we need to multiply it by π180. This is because there are 180o degrees in a radian. So, 4πc× π180 =720o. Let's break it down step …

Simply click the π symbol on the calculator then the calculation you want to carry out.

If it were 4piε then Gauss's law would be flux=q/4pi which isn't desirable. Since we can't change ε, we also can't change μ since εμc 2 =1, where c is the speed of light.

According to the question we have to calculate the value of 4 π in degrees. Here, if we see then one radian contains 180 ∘ and that is equal to half circle’s angle. So, for making a complete …

What is the value of sin (4pi) ?
