How do you find the diamter of a circle if you know the area?
In order to find the diameter of a circle if you have the area is to rearrange the formula for the area of a circle to put diameter as the unknown, like so: PIE*d = Area of a Circle d = (Area of a Circle) / PIE Therefore if the area of your circle is 40cm, 40/PIE = 12.73cm and that's the diameter.
How many tiles 50cm by 50cm can fit into a 1m square?
To find out how many 50cm by 50cm tiles can fit into a 1m square, we first need to convert the measurements to the same units. Since 1m is equal to 100cm, a 1m square is equivalent to a 100cm by 100cm square. To calculate how many 50cm by 50cm tiles can fit into this square, we divide the area of the 1m square by the area of each tile (100cm by 100cm ÷ 50cm by 50cm). This gives us 4 tiles that can fit into a 1m square.
