Since you said 'diameter', I assume you mean finding the area of a circle with diameter 5 meters.
The formula for finding area of a circle is pi X (radius squared) OR pi X radius X radius.
Diameter = 5m, Radius would be 5m/2 = 2.5m
So the area of the circle would be 3.141592... … Read more

To convert a mixed number e.g. 4 8/9 to an improper fraction,
1. Take the whole number (4).
2. Multiply that by the denominator (9). (4 X 9 = 36)
3. Add this number to the numerator (8). (36 + 8 = 44)
The improper fraction will be: 44/9 (44 is the number you got … Read more
3/5 ------ = 0.60000
33/50 ------ = 0.66000 <--
303/500 ------ = 0.60600
3003/5000 --- = 0.60060
30003/50000 = 0.60006
33/50 is the greatest.
The 'tenth' place is the number 4.
First, look at the number to the right.
If the number is 5 or less, just take away all the digits to the right of 4 in this case.
If the number is more than 5, add 1 to 4 which gives 5, then take away all the … Read more
In 6 / ? = 2 you know ? = 3 and 6 / 2 = 3 so 6 / 2 = ?.
In the same way 50 / ? = 2.5 so 50 / 2.5 = ?.
50 / 2.5 = 20
On a normal calculator you can type words into a calculator.
