The area of central circle would be : pi. d^2 /4

the area of the next region would be :  pi ( d^2  - d^2/4) = 3/4 pi d^2

The outermost region would be : pi (9d^2 / 4 - d^2/4) = 5/4 pi d^2

What is the reason behind hamlet and Ophelia’s argument
Marysya12 [62]
Angrily, Hamlet denies having given her anything; he laments the dishonesty of beauty, and claims both to have loved Ophelia once and never to have loved her at all. Bitterly commenting on the wretchedness of humankind, he urges Ophelia to enter a nunnery rather than become a “breeder of sinners” (III.i.122–123).
