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
