Question

A circle of radius 2 cm is cut out from a square piece of an aluminium sheet of side 6 cm. What is the area of the left over aluminium sheet?( Take pie- 3.14)

Answer 1

36-(3.14*4) = 23.44cm2

Answer 2

Answer:

$\red{Area \:of \:the \: left \:over \: aluminium\:sheet}$

$\green {= 23.44\: cm^{2}}$

Step-by-step explanation:

$Side \: of \: a \: square \:piece \:of \:an \\aluminium \: sheet (a) = 6\:cm$

$\boxed { \pink {Area \:of \:a \:square = a^{2}}}$

$Radius \: of \: a \:circle (r) = 2\:cm$

$\boxed {\orange { Area \:of \:a \:Circle = \pi r^{2}}}$

/* According to the problem given

$Area \:of \:the \: left \:over \: aluminium\:sheet$

$= Area \: of \:the \:square - Area \:of \:the \: circle$

$= a^{2} - \pi r^{2}\\= 6^{2} - 3.14 \times 2^{2}\\= 36 - 3.14 \times 4\\= 36 - 12.56\\= 23.44\: cm^{2}$

Therefore.,

$\red{Area \:of \:the \: left \:over \: aluminium\:sheet}$

$\green {= 23.44\: cm^{2}}$
