In order to find the area of a circle use the formula:
π
Where r is the radius
For example the radius is 3cm. The area of the circle will be:
π × 
Since you have taken pi as 3.142...
3.142 ×
3.142 × 9
= 28.278
In order to find the answer to 1 decimal place, check the number next to the number right after the decimal. Is it a number greater than or equal to 5? then add +1 to the number.
= 28.3

- 100% = 50 questions
- 2% = 1 question
- 92% = 46 questions
Answer:

4. 200%
Step-by-step explanation:
Here, we want to find the worth of each coin as a percentage of $1
We simply divide the worth by $1 and multiply by 100%
$1 is same as 100 cents
Thus;
1. 50 cent
= 50/100 * 100% = 50%
2. 3 cents
= 3/100 * 100% = 3%
3. 20 cents
= 20/100 * 100% = 20%
4. $2
= 2/1 * 100% = 200%
