Автор ответа: EnotLily

1) радиус равен 12 см
диаметр= радиус х (умножить) 2
значит, чтобы найти диаметр нужно радиус умножить на 2
12х2= 24см
2) радиус равен 5 мм
5х2=10мм (1 см)
3) радиус равен 10 дм
10х2= 20 дм

The United Kingdom is an abbreviation of 'the UK of Great Britain and Northern Ireland'. It is often abbreviated to 'UK', and is the political name of the country which is made of England, Scotland, Wales and Northern Ireland. In everyday speech 'Britain' is used to mean the UK.
Britain is one of the world's smaller countries with an area of some 244,100 square kilometres; with some 56 million people, it ranks about 14th in terms of population.
Britain is the world's third est trading nation, accounting for about 11 per cent of international trade in manufactured goods. Over a quarter of total exports go to Commonwealth countries and over a third to Western Europe. The US, Canada, Australia, India, New Zealand and the Federal Republic of Germany are among Britain's chief trading partners.
Metal and metal-using industries contribute more than 50 % of the exports. Britain imports all of its cotton, rubber, sulphur, 80% of its wool, half of its food and iron ore, also certain amounts of paper, tobacco, chemicals. Manufactured goods made from these basic materials are sent all over the world. Main exports are machinery, chemicals, woollen and synthetic textiles, clothing, autos and trucks, iron and steel, locomotives, ships, jet aircraft, farm machinery, drugs, radio, TV, radar and navigation equipment, scientific instruments, arms, whisky. Invisible exports — shipping, insurance, aviation, tourism, etc. — earn nearly as much as commodity exports
