Question

Four equal sized maximum circular plates are cut off from a square paper sheet of area 784 $c{m}^2$, The circumference of each plate is......

• A. 22 cm
• B. 44 cm
• C. 66 cm
• D. 88 cm

Answer 1

The correct option is B 44 cm

square paper sheet of area = 784 $c{m}^2$
Let's assume side of square paper sheet =a
So, $a^2=784$
$a=28$
As per question,Diameter =28/2=14cm, radius=14/2=7cm
circumference of each plate=
$C=2\Pi r=2\times \frac{22}{7}\times 7==44cm$
Answer (B) 44 cm
