Question

If square sheet of area 3.14 $c{m}^2$ is shaped into circular sheet, then find the circumference of that sheet(use pi=3.14)

• A. 3.14 cm
• B. 4.42 cm
• C. 6.28 cm
• D. 7.84 cm

Answer 1

The correct option is C 6.28 cm

Since the square sheet is shaped into circular sheet,
Area of circle = Area of square sheet
3.14$\times$$\pi \times$$r^2$ = 3.14
$r^2$ = 1
r = $\sqrt{1}$ = 1
circumference of circle = 2$\pi$r
= 2$\times$3.14$\times$1
= 6.28 cm
