Hi,

We can solve this question without finding out exact value as well.

Total area of circle = 25p

Now the area covered by cow should be = 3/4 of total area of circle + some small areas near the rectangle .i.e 18p + something.

Option gives only one such value that is 20p.

Cheers!!

I am writing GRE in August.

Yes, great way of thinking! And a great way to save time.

It’s exactly this logic that will help you do well test day :).

Its E, 20 pi

Good job
