Question

If the parimeter of the circle is equal to that of a squuare .Then the ratio of their areas is

Answer 1

Answer:

4:π

Step-by-step explanation:

let r is the radius of the circle then perimeter is 2πr

area is πr²

if s is the side of a square then perimeter is 4s

area is s²

given that 2πr=4s

r=2s/π

then πr²:s²

=π*4s²/π² : s²

=4/π : 1

=4:π
