The area of a 5p coin, which is a British five pence piece, can be calculated using the formula for the area of a circle (A = πr²). The diameter of a 5p coin is approximately 18mm, giving it a radius of about 9mm. Therefore, the area is approximately 254.47 mm² when using π ≈ 3.14.

A 5p coin weighs 3.25 grams. To find out how many 5p coins are in a kilogram (1000 grams), you divide 1000 by 3.25, which gives you approximately 307.69. Therefore, there are about 307 five-pence coins in a kilogram.
Well, isn't that a happy little riddle! If one of the coins is not a 10p coin, then it must be a 1p coin. So, you have a 10p coin and a 1p coin in your hand, making a total of 11p. Just like painting, sometimes it's the small details that make the big picture come together beautifully.
To calculate the number of 5p coins in £17, we first need to convert £17 to pence. Since there are 100 pence in £1, we multiply 17 by 100 to get 1700p. Then, we divide 1700 by 5 (the value of each 5p coin) to find that there are 340 5p coins in £17.
