Question

The radivs of circle is 14cm and the side of square is 8cm, which has great area and by how much which has less perimeter and by how many?

Answer 1

$area \: of \: circle \: = \pi {r}^{2} \\ = 22 \times 14 \times 14 \div 7 \\ = 616 \: sq \: cm$
$cirumfernce \: of \: circle \: = \pi2r \\ = \pi \times 2 \times 14 \\ = 88 \:\: cm$

similarly Calculare area of square by side^2 and perimeter by 2×side
