From A student: given a circle and square of same perimeter, why does the circle have a larger area
I’m looking for an intuitive explanation rather than a computational one. Thanks Answered by Harley Weston. 





The area of a circle and a square

From Richard: I cannot understand why if you have a perimeter say of 4 units as the circumference of
a circle then you reshape it into a square you lose very approximately some 20% of its
volume but the perimeter length stays the same.
Can you please explain this to me as to why the volume decreases. Answered by Penny Nom.
