Answer:

I don't know the raduis so I can't exactly sovle it for it but I can help you

Explanation:

So I'm going to use 3 as the radius as an example but when you do it, don't use 3 unless its the radius.

So first find the area of the entire circle and to do that, you do 3.14 times 3 times 3. (a=pi*raduis sqaured) 3.14*3*3 is 28.96. So 28.96sqaured is the area of the entire circle but the question wants 1/4 of the circle's area so you divide it by 4 which gets you 7.065. Rounded up since 6 is over 5 and that would be 7.1. The area of 1/4 a circle of the example I gave is 7.1 sqaured.

This is not the answer to your question btw this is an example since I do not know what the radius for your question is.

What you have to do is 3.14 times(the radius) times(the raduis). When you get your answer divide that by 4 so you get 1/4 of the area since that's what the question is asking.

Hope this helps and if you can tell me the radius, I can help you sovle it:)

If the radius is 1.3 then the answer should be 1.3 sqaured. The exact answer is 1.32665 if you need that instead
