<h3>Answer: ok so if the radius of the circle is one all you need to doto find the diameter is multiply it by 2 becuase the diameter is twice the radius and the radius is half the diameter for instance..if you had a diameter of four the radiace would be two becuase half of four is two.</h3><h3>So the formula to find the cicumfrance of a circle is C=2pir</h3><h3>its basically just taking the radiace which in your case is one and multaplying it by two..ok so your like now i have two what do i do..? Well thats it the answer is 2pi you would have to add the pi symbol
<--- now if it has a number in replace of the pi say 3.14, alright your like i have two and i have 3.14 what do i do...you would just have to multiply the 2 by 3.14 to get an answer of....6.28!</h3>
Explanation: I hope this helps...:D
Answer:
Nuclear weapons are weapons of mass destruction. That's why many countries and international organizations are trying to limit its testing: when a nuclear weapon explodes, a lot of energy is released in the form of heat, pressure wave and ionizing radiation. As a result, a nuclear weapon can quickly destroy an entire city and kill hundreds of thousands of people. The radiation causes acute radiation sickness and long-term damage to health.
Because of the enormous destructive power of nuclear bombs, efforts have always been made to abolish all nuclear weapons and to generally ban them in order to prevent them from being destroyed. The Cold War and the power interests of individual nations, however, prevented a rapid abandonment of weapons of mass destruction. Nevertheless, some agreements were implemented, each of which signaled a major step towards a world free of nuclear weapons. However, it is doubted whether the agreements are actually as effective as desired.
