Answer:
First you find the radius R
We have, circumference = 2*3.14*R = 31.4
=> R =31.4/(2*3.14) =5
We have , area = 3.14*R^2 = 3.14*5^2 = 78.5
Step-by-step explanation:
Here we use pi =3.14.
So basically a decimal is moved based on how many zeros are in the dividing number
Ex. 51,000/100
because there are 2 zeros in the number one hundred, the decimal in 51,000 gets moved 2 places to the left
So it goes from 51,000 to 510
Ex. 16 * 1000
There are three zeros in the number 1000. This means three zeros will be added onto the number 16
So the answer would be 16,000
Hope this helps!
