Question

If the perimeter of a circle is half to that of a square then the ratio of the area of the circle to the area of the square

Answer 1

Step-by-step explanation:

2πr=(4a)/2

on solving

πr= a ==>(r/a)=(1/π)

${r}^{2} \div {a}^{2} = 1 \div {\pi }^{2} \\ \\ \pi {r}^{2} \div {a}^{2} = 1 \div \pi$
