Question

find the area of a circle who's diameter is 4.7 cm

Answer 1

Heya !!





Diameter of circle = 4.7 cm.




Radius = D/2 = 4.7/2 = 2.35 cm.




Area of circle = πr²




=> 22/7 × 2.35 × 2.35




=> 17.35 cm². [ Approx ]

Answer 2

diameter=4.7
radius=4.7/2

$area = \pi {r}^{2} \\ area = \pi { (\frac{4.7}{2}) }^{2} \\ area = 5.522\pi$
