Find the area covered by a circular plate whose radius is 4.9 cm.​

Answer 1

$\bold{Question:-}$

• Find the area covered by a circular plate whose radius is 4.9 cm

$\bold{To\:Find:-}$

• Area of circular plate

$\bold{Given:-}$

• Radius = 4.9 cm

• $\pi = \frac{22}{7}$

$\bold{Required\:Formula:-}$

$\implies$ Area of circle = $2\pi r$

$\bold{Solution:-}$

Applying the values by the given formula,

$\implies \frac{22}{7} \times 4.9^2$

$\implies \frac{22}{7} \times 4.9 \times 4.9$

$\implies 22\times 0.7 \times 4.9$ = 75.46 cm^2

$\therefore$ The area of a circular plate is 75.46 cm^2
