Work out the area of this circle. Take pi to be 3.142 and give your answer to 1 decimal place

Step-by-step explanation:

I think you have forgotten to attach the question.

Anyways....

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

answer: 1, 3 and 5 are correct
