Question

Find the area of circle whose diameter is 12 cm with pie 22/7

Answer 1

area of circle = (pie) r^2
= 22/7 × 6×6. ( radius= 6cm)
= 113.04 cm^2

Answer 2

Area of the circle =
$area \: of \: the \: circle = \pi \: r {}^{2}$
$\: \: \: \: \: \: = 22 \div 7 \times 6 \times 6$
$\: \: \: \: \: \: \: = 22 \times 36 \div 7$
$\: \: \: \: \: \: = 792 \div 7$
$\: \: \: \: \: = 113.142857142857$
